Reference no: EM13653130

A 13 g projectile traveling 153 m/spenetrates into a 0.25-kg wad of putty and emerges cleanly at28 m/s.

a) If the putty is stationary on a frictionless surface when hit, how fast does it move after the projectile emerges?

b) How much kinetic energy was lost in this process?
