The x- and y-components of the velocity vector shown in the figure are -50m/s and -86.6m/s respectively.

A velocity vector is defined as the rate of position change of an object. The magnitude of a velocity vector gives the speed of an object while the vector direction gives its direction. The horizontal velocity component (Vx) refers to the influence of the velocity in displacing the projectile horizontally. The vertical velocity component (Vy) refers to the influence of the velocity in displacing the projectile vertically.

The Vx = VcosƟ and Vy = VsinƟ where Ɵ is the angle between the velocity vector and x-axis

Answer: 10 seconds for the car to go from a velocity of 10 m/s to 30 m/s with an acceleration of 2 m/s^2.

Explanation:

To calculate the time it takes for a car with an acceleration of 2 m/s^2 to go from a velocity of 10 m/s to a velocity of 30 m/s, we can use the equation:

time = (final velocity - initial velocity) / acceleration

In this case:

time = (30 m/s - 10 m/s) / 2 m/s^2

time = 20 m/s / 2 m/s^2

time = 10 s

Therefore, it takes 10 seconds for the car to go from a velocity of 10 m/s to 30 m/s with an acceleration of 2 m/s^2.

Answer:

Explanation:

The power is calculated by the equation Power = Work/Time.

Work = Force x Distance

Work = 500 N x 15 m = 7500 Nm

Time = 14 seconds

Power = 7500 Nm/14 s = 535.7 W (rounded to one decimal).

The mass would gain twice the kinetic energy it did in the scenario above if the spring were compressed by 14.1 cm.

A particle or perhaps an item that is currently motion has a type of energy called kinetic energy. An item acquires kinetic energy when work, which involves the transmission of energy, is performed on it by exerting a net force.

A spring's energy reserve is proportional to the square of the compression, x.

PE of compression = 0.5kx^2 where k is a constant to do with how easy it is to compress the spring.

So 0.5d^2 gives a KE of value Q

If you double Q you get 2Q and get 0.5D^2 where D is the new compression

So 0.5d^2/0.5D^2 = Q/2Q

d^2/D^2 = 1/2 which means that D^2 = 2d^2 or D = d(sqrt2)

Therefore, the new compression is roughly 1.414 times that of the old one.

Easiest method for recalling is that KE is proportional to sqrt(d)

To double KE you need to compress the spring sqrt2 times as much as before.

Hope this helps.

PE of spring = stored energy = (1/2)kx^2 = (1.2)mv^2

So kx^2 = mv^2

x^2 = (m/k)v^2

x is proportional to v

If x is doubled, v is doubled, and the KE is quadrupled.

Velocity at which the car can take the curve without skidding to the outside of the curve is approximately 29.5 m/s.

To determine the speed at which the car can take the curve without skidding to the outside of the curve, we need to calculate the maximum force of static friction that can act on the car as it goes around the curve.

The maximum force of static friction can be found using the formula:

f_max = friction_coefficient * f_norm

where f_max is the maximum force of static friction, friction_coefficient is the coefficient of static friction between the tires and the pavement (0.87), and f_norm is the normal force acting on the car.

The normal force can be found by calculating the centripetal force acting on the car as it goes around the curve, which can be found using the formula:

f_cent = m * a_cent

where f_cent is the centripetal force, m is the mass of the car (1091 kg), and a_cent is the centripetal acceleration, which can be found using the formula:

a_cent = v² / r

where v is the velocity of the car and r is the radius of the curve (36 m).

Substitute the value of a_cent in the formula for f_cent

f_cent = m * (v² / r)

Also we know that the maximum force of static friction is equal to the normal force acting on the car

f_max = f_norm = m * (v² / r)

Now we know friction_coefficient * f_norm = m * (v² / r)

so we can substitute the value of friction_coefficient and m and r

0.87 * m * g * sin(25) = m * (v² / 36)

v = √(0.87 * 9.8 * 36 * sin(25))

v = 29.5m/s

Therefore, the velocity of the car without skidding outside the curve is 29.5m/s
