Academics

A 500 gram dynamics cart starts at rest and rolls down a track thatis 2.5 meters long and elevated 15 cm on one end. At thebottom of the track it rolls onto a level surface and then collideswith a 1200 g cart that is sitting still. The collision isperfectly inelastic.

1. Find the speed of the first cart when it reaches the bottom ofthe incline. (assume no friction) (1.7m/s)

2. Determine the speed of both carts after the collision(0.5 m/s)
