Answer to Question #193653 in Classical Mechanics for Kaitlyn Hosking

Question

3. A truck of mass 2000kg, moving at 20m/s, collides with a car of mass 1000kg, which is stationary. What is the velocity of the car after the collision if the truck now moves 

forward at 10m/s ?

4.A skater of mass 70 kg is moving at 4 m/s when he bumps into a skater of mass 50 kg who is not moving.  They move off together on the ice.  What is their velocity immediately after the collision?

5.In a game of bowls one particular bowl hits the jack head on causing it to move forward. The jack has a mass of 300 g and was originally stationary.  The bowl has a mass of 1 kg and was moving at a speed of 2 m/s before hitting the jack, but continued forwards at 1.5 m/s after the collision.  What is the speed of the jack after the collision?
