Solution: A 5 kg mass moves with an initial speed of 1 m/s and collides with a 10 kg mass at rest. After the collision, the 5 kg mass is at rest and the 10 kg mass is in motion, with some speed v. (a) What type of collision is this? (b) What is the speed v? (c) IF the collision is inelastic, how much kinetic energy was lost during the collision?
