a 100 g ball moving to the right at 4 meters per second collides head- on with a 200g ball that's moving to the left at 3m/s. if the collision is perfectly elastic, what are the speeds of each ball after the collision
if the collision is inelastic, what's the speed of the combined balls after the collision?
