PROBLEMS:
1. A motionless catapult was aimed horizontally and fired a 10.0 kg wood block due west at 50
m/s. If the catapult's mass was 250 kg, what is the recoil velocity of the catapult if friction is
ignored?
2. A car of 500 kg, traveling at 30 m/s rear ends another car of 600 kg, traveling at 20 m/s. in
the same direction The collision is great enough that the two cars stick together after they
collide. How fast will both cars be going after the collision?
3. A boy of 50 kg mass is running with a velocity of 2 m/s. He jumps over a stationary cart of 2
kg while running. Find the velocity of cart after jumping of the boy.
4. A car of 400 kg, traveling at 20 m/s rear ends another car of 600 kg, traveling at 15 m/s. in
the same direction The collision is great enough that the two cars stick together after they
collide. How fast will both cars be going after the collision?
