A ball is thrown upwards. At the instant it reaches its maximum height, what is the direction of its momentum?
A 2 kg object moves to the right with a velocity of 5 m/s, and a 3 kg object moves to the left with a velocity of 2 m/s. What is the magnitude of the total momentum of the system?

A 4 kg bowling ball moving at 5 m/s strikes a 1 kg pin, which subsequently moves forward. If the bowling ball's speed is reduced to 3 m/s after the collision, what is the speed of the pin immediately after the collision, assuming the collision is perfectly inelastic?
A collision occurs between two objects in an isolated system. Which of the following statements is true regarding kinetic energy and momentum?
Two carts collide on a frictionless track. Cart A has a mass of and an initial velocity of to the right. Cart B has a mass of and is initially at rest. After the collision, the two carts stick together. What is the final velocity of the combined carts?
