Answer:
The spring constant is 907.2 N/m
Explanation:
v^2 = u^2 + 2as
Where:
v = final velocity
u = initial velocity
a = acceleration
s = displacement
As the spring is clamped to the table, the only displacement is horizontal, so the only acceleration is due to gravity. The final velocity is 0, as the ball lands on the floor. Therefore, we can use the equation of motion to determine the initial velocity of the ball:
v^2 = u^2 + 2as
0 = u^2 + 2g(1.6 m)
u = √ (2g(1.6 m))
We know that acceleration due to gravity is 9.8 m/s^2, so:
u = √ (2 * 9.8 * 1.6) = 4.6 m/s
Now we can use the conservation of energy to solve for the spring constant.
The spring constant can be determined by using the equation:
PE = 1/2 kx^2
where PE is the potential energy stored in the spring, k is the spring constant, and x is the compression of the spring.
KE = 1/2 mv^2
where KE is the kinetic energy of the ball, m is the mass of the ball, and v is the initial velocity of the ball
The sum of the potential energy stored in the spring and the kinetic energy of the ball is conserved, so:
1/2 kx^2 = 1/2 mv^2
We can now substitute the values we know into the equation:
1/2 k * (0.2)^2 = 1/2 * (19g) * (4.6m/s)^2
Solving for k:
k = (19g * (4.6m/s)^2 ) / (0.2m)^2
k = 907.2 N/m
Note that the unit of mass is gram (g) and it needs to be converted to kg to make the units consistent.
how would you describe the motion of plates in a transform boundary?
As the plates separate from one another, the transform boundary is described. Assume that two crusts are present and that they exactly line up from east to west. A plate drifts north, away from another plate.
What is the transform plates motion?The transform fault, a third type of plate boundary, allows plates to slide past one another without creating or destroying crust. Rocks facing each other on two sides of the fault are typically of different type and age because they are cut and displaced by movement in the opposite direction.
Two plates collide at the transform plate boundary when they slide past one another horizontally. The San Andreas Fault, which causes a large number of earthquakes in California, is a well-known transform plate boundary.

Two 3. 0 g bullets are fired with speeds of 40. 0 m/s and 80. 0 m/s, respectively. What are their kinetic energies? which bullet has more kinetic energy? what is the ratio of their kinetic energies?.
For the first bullet, kinetic energy is 480 J and for the second bullet, kinetic energy is 1920 J.
What is kinetic energy?Kinetic energy is the energy possessed by an object or a particle due to its motion. It is the energy of motion and can take many forms, such as the energy associated with an airplane flying through the air, a ball rolling down a hill, a person running, or a car traveling on a highway. In general, kinetic energy is the energy an object has because of its movement.
The kinetic energies of the two bullets can be calculated using the equation KE = (1/2)mv2, where m is the mass of the object and v is the velocity of the object.
For the first bullet, KE = (1/2)(3.0 g)(40.0 m/s)2 = 480 J.
For the second bullet, KE = (1/2)(3.0 g)(80.0 m/s)2 = 1920 J.
The second bullet has more kinetic energy than the first bullet. The ratio of their kinetic energies is 4:1. This means that the second bullet has four times more kinetic energy than the first bullet.

A 2350 kg shark moves upward toward a 195 kg fish that is at rest and swallows it whole. How much energy (fraction or percent of
initial energy) was lost in the collision?
The initial energy was lost in collision of a 2350 kg shark moves upward toward a 195 kg fish that is at rest and swallows it whole = 95.33 Joules.
Perfectly inelastic collisions, in contrast to elastic collisions, conserve momentum but not energy. The kinetic energy carried by the moving objects is not always conserved, even though the system's overall energy is always constant. Energy lost to the environment and converted into other forms, such heat, during an inelastic collision.
To determine the energy lost in collision, use the equation:
E = ½ (m1m2) / (m1 + m2) x v²
Where:
m 1 = mass of the object 1
m 2 = mass of the object 2
v 1 = velocity /speed of the object 1
v 2 = velocity / speed of the object 2
v 1 = v2
Hence,
E = ½ (2350 x 195) / (2350 + 195)

If a ball i thrown horizontally from the roof of a building 55 m tall with a speed of 3. 8 m/ so the ball will land 55 m away from the building.
What is speed?Speed is the rate at which something moves or occurs. It is usually measured in terms of distance over time. Speed can be expressed in many different forms, including miles per hour (mph), kilometers per hour (kph), meters per second (m/s) and even in terms of the speed of light. Speed is a measure of how quickly something moves in a specific direction.
The ball will land 55 m away from the building. This is because the horizontal velocity of the ball is 3.8 m/s, and the time it takes to travel 55 m is 55/3.8 = 14.47 seconds. Since the ball was thrown horizontally, it will travel a horizontal distance equal to the time it took multiplied by the velocity, which is 14.47 * 3.8 = 55 m.

Does mass depend on speed?.
No, mass and speed are two different physical quantities that do not have any direct relationship.
Mass is a scalar quantity that measures the amount of matter in an object, it is independent of its location or motion and it is constant. It is the same whether an object is at rest or in motion.
Speed, on the other hand, is a measure of how fast an object is moving. It is the distance an object travels in a certain amount of time and it can change. For example, an object can be moving at a high speed or at a low speed.
In the theory of special relativity, mass and energy are closely related and, as a result, the mass of an object increases as it approaches the speed of light. But this is only for objects that are moving at a velocity close to the speed of light, but for everyday objects, mass does not depend on speed.
So, the mass of an object does not change with its speed, but the energy of an object does increase as its speed increases.

To calculate the water pressure that acts on the hull of the boat, we can use the equation:
Pressure = Force / Area
The force acting on the hull is the buoyant force, which is equal to the weight of the water displaced by the boat. Since the boat is floating, the weight of the water displaced is equal to the weight of the boat. Therefore:
Force = Weight of boat = 20,000 N
The area of the hull that is in contact with the water is 4 m2
Therefore, the water pressure acting on the hull of the boat is:
Pressure = Force / Area = 20,000 N / 4 m2 = 5000 N/m^2
The pressure unit is Newtons per square meter (N/m^2) also known as Pascals (Pa).

What's the difference between Newton's first law and inertia?.
Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity unless acted upon by an unbalanced force. In other words, it states that an object will remain in a state of constant velocity unless acted upon by a net external force.
Inertia, on the other hand, is the property of an object that resists a change in its state of motion. It is the tendency of an object to maintain its current state of motion (i.e. at rest or in motion) unless acted upon by an external force. Inertia is a fundamental concept in physics and is closely related to Newton's first law.

Does gravity depend on size or density?.
Gravity depends on mass, not on size or density.
Gravity is a force of attraction between two objects that have mass. The force of gravity is proportional to the product of the two masses and inversely proportional to the square of the distance between them. Therefore, the more massive an object is, the stronger the gravitational force it exerts.
Size and density are not directly related to gravity. Size is a measure of how big an object is, and density is a measure of how much mass is contained in a given volume. They do not affect the strength of the gravitational force. An object's size or density may affect the gravitational force acting on it, but only through their effect on the object's mass.
