5. A bullet of mass m = 0.02kg exits a gun at a velocity vo= 500 m/s and collides with a stationary block of mass M = 2kg. The bullet passes through the block and emerges with a speed v = 100 m/s. After the collision, the block moves on a frictionless surface a distance d = 1m until it comes D k F= Fe a. Find the velocity of the block after the collision. b. Find the energy that was lost in the collision.
