A spinning sphere has a moment of inertia of 12 kg.m^2 and has an angular momentum of 18 kg.m^2/s. What is the angular speed of the sphere?
There are two billiard balls each with a mass of 200 g. A pool player shoots Ball A with a velocity of 1.0 m/s at Ball B, which is at rest. After an elastic collision, Ball A stops and Ball B travels off in a straight line. What is the velocity
A batter applies a constant force of 10.0 N over a period of 5.00 milliseconds when he strikes a baseball. The mass of the baseball is 145 g. What is the magnitude of the velocity change of the baseball?
A 10-kg cart moving to the right at 5 m/s has a head-on collision with a5-kg cart moving to the left at 7 m/s. If the carts stick together, what is the velocity of the combination?
The video camera used in the experiment in the question above has a frame rate of 30 pictures per second. In the video, the ball makes contact with the floor for three frames. What is the average force that the ball exerts on the floor?
A rifle fires a 4.0-g bullet at a velocity of 950 m/s. If the bullet is in the rifle barrel for only 0.1 s, what average force does the rifle exert on the bullet?
The moment of inertia of a particular thin-walled cylinder around its central axis is given by mR^2. What expression best represents the angular momentum of this cylinder if it spins about the central axis at a rate of 12 revolutions per second?
A stationary curling stone is struck in a glancing collision by a second curling stone of equal mass. If the first stone moves away at a velocity of 0.92m/s [N71degreesW] and the second stone moves away at a velocity of 1.25m/s [N44degreesE], what is the
A 10-N force is applied to a hockey puck over a period of 0.1 s. What is the change in momentum of the hockey puck?
A 1000-kg car moving at a constant velocity of + 11.0 m/s strikes a concrete barrier and comes to a complete stop in 2.0 s. What is the average force acting on the car?
