Physics Review Sheet Chapter 9 1. What is the momentum of a 115g tennis ball traveling at 47 m/s? 2. A 7500 N force is applied to stop a car that has a mass of 2300 kg traveling at 22m/s. How long does the force need to be applied? 3. A rubber ball with a mass of 85 g is rolling on a surface at 2.2 m/s. It strikes a steel ball with a mass of 185 g and stops. What will be the velocity of the steel ball after the collision? 4. An 86 gram bullet traveling at 1200 m/s East strikes a 2.5 kg block of wood. The bullet lodges in the block. What is the velocity of the block and bullet after the collision? 5. A wagon with a mass of 15 kg moving at 8.4 m/s East strikes a bicycle that has a mass of 25 kg and is moving at 13.5 m/s West. After the collision, the wagon is moving at 2.3 m/s West. What is the velocity and direction that the bicycle moves after the collision? Construct a diagram.
