Is magnitude of vector negative or positive?.

To determine the average velocity in meters/second, we need to convert the distance from miles to meters and the time from minutes to seconds.

To convert miles to meters, we multiply by 1609.34.

To convert minutes to seconds, we multiply by 60.

So, distance = 25 miles * 1609.34 meters/mile = 40233.5 meters

time = 25 minutes * 60 seconds/minute = 1500 seconds

Average velocity = distance / time = 40233.5 meters / 1500 seconds = 26.856 meters/second

To determine the average velocity, we need to calculate the total distance traveled and divide it by the total time taken.

Distance = 35 meters + 45 meters + 65 meters = 145 meters

Time = 85 seconds

Average velocity = distance / time = 145 meters / 85 seconds = 1.71 meters/second

To determine the average speed, we just need to calculate the total distance traveled / total time taken.

Average speed = distance / time = 145 meters / 85 seconds = 1.71 meters/second

To determine the distance traveled, we need to add the distance traveled in each direction: 75 kilometers + 25 kilometers + 75 kilometers = 175 kilometers.

To determine the displacement, we need to calculate the final position of the car relative to its initial position. Displacement is a vector quantity, so it takes into account the direction of the motion. The car traveled north 75 kilometers, then west 25 kilometers, then south 75 kilometers. So, the final position of the car is 25 kilometers west of its initial position. Therefore, the displacement of the car is 25 kilometers west.

Answer:

Physics problem solutions

1 To determine the average velocity of the car, you will need to divide the distance traveled (in meters) by the time it took to travel that distance (in seconds).

First, you will need to convert the distance from miles to meters.

1 mile = 1609.344 meters

So 25 miles = 40,233.6 meters

Then, you will need to convert the time from minutes to seconds.

1 minute = 60 seconds

So 25 minutes = 1500 seconds

Average velocity = distance traveled / time = 40,233.6 meters / 1500 seconds = 26.822 m/s

2 To determine the average velocity and average speed, you will need to divide the distance traveled (in meters) by the time it took to travel that distance (in seconds).

Distance traveled: 35 meters + 45 meters + 65 meters = 145 meters

Average velocity = distance traveled / time = 145 meters / 85 seconds = 1.71 m/s

Average speed = total distance / total time = (35 + 45 + 65) / 85 = 2.71 m/s

3 To determine the distance the car travelled, you will need to add up the distance traveled in each direction.

Distance traveled = 75 km + 25 km + 75 km = 175 km

To determine the displacement of the car, you will need to find the straight-line distance and direction from the starting point to the ending point.

Displacement = sqrt(75km^2 + 75km^2) = sqrt(5625 + 5625) = sqrt(11250) = 105.8 km, this is the north-south distance,

It's important to notice that the displacement is a vector quantity that has a magnitude and direction, and displacement is not the same as distance.

Torque is calculated using the formula, τ = r × F, where, r is the perpendicular distance, F is the force.

It is also described as the cross product of distance vector and force vector. Mathematically, τ = r × F = r F sinθ, where, θ is the angle between r and F.

For example, a force is applied to a particle free to rotate about a fixed axis. Force is shown divided into perpendicular and parallel components. Torque is pointed outward from the page and has the magnitude

τ = r F sinθ.

Newton-meters, sometimes known as N.m, are the SI units for torque. Although these units are the same as joules, torque isn't considered to be work or energy, therefore N.m should be used instead.

Work done when a 100 lb rock is lifted to height of 3 ft is 9652.215 ft-lb.

The work done on an object is equal to the force applied to it multiplied by the distance over which the force is applied. In this case, the force applied is the weight of the rock, which is equal to the force of gravity acting on it.

The weight of an object is given by the formula:

W = mg

Where m is the mass of the object (in this case, 100 lb) and g is the acceleration due to gravity (approximately 9.8 m/s^2 or 32.17405 ft/s^2).

So the weight of the rock is:

W = (100 lb)(32.17405 ft/s^2) = 3,217.405 ft-lb

The work done on the rock is equal to the force applied (its weight) multiplied by the distance it is lifted (3 ft), so the work done is:

Work = (3,217.405 ft-lb) x (3 ft) = 9652.215 ft-lb

There are three laws of motion described by Sir Isaac Newton. These laws describe the behavior of objects in motion and form the foundation of classical mechanics. The laws are as follows:

1. The first law 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 external force. This is often referred to as the law of inertia.

2. The second law states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. The acceleration of an object is given by the equation F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.

Momentum is a measure of an object's motion.

Momentum is the product of an object's mass and velocity, and is represented by the symbol "p." In physics, momentum is considered to be a vector quantity, meaning it has both magnitude and direction.

The basic equation for momentum is p = m*v, where "m" is the object's mass and "v" is its velocity. This equation states that the momentum of an object is directly proportional to its mass and velocity. In other words, an object with a greater mass or a greater velocity will have a greater momentum.

An important concept in physics is that momentum is conserved. This means that in a closed system, the total momentum before a collision or any other interaction is the same as the total momentum after the collision. It also means that the momentum of an object or system of objects cannot be created or destroyed, it can only be transferred or exchanged.

Momentum also plays an important role in many areas of our everyday lives, for example in sports, where a player has to transfer a lot of momentum to hit a ball with a bat. It also plays a role in transportation, where vehicles have to have a certain amount of momentum to move and maintain the velocity.

In summary, momentum is a measure of an object's motion, and it is directly proportional to the mass and velocity of the object. It is a vector quantity and conserved in closed systems. It plays an important role in many areas of physics, and in our everyday lives.
