Two railroad cars (2 X 10^4 kg each) are traveling in the same direction along a railroad track. Car A is traveling at 14 m/s, and Car B is traveling at 10 m/s. When Car A catches up with Car B, the two cars link together. What is the velocity of
A bullet has a mass of 50 g, and its momentum is 25 kg.m/s. What is the velocity of the bullet?
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?
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 10-kg box is sliding across an ice rink at 10 m/s. A skater exerts a constant force of 10 N against it. How long will it take for the box to come to a complete stop?
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 0.5-kg object has a momentum of 10 kg.m/s. What is its speed?
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?
Consider the collision shown to the right. M1 is moving to the right at 12 m/s. M2, that has one-sixth of the mass of M1, is moving to the left at 3.4 m/s. How fast will M2 be moving after the collision? (Assume the table is frictionless)
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?
