Croquet ball A moving at 8.7 m/s makes a head on collision with ball B of equal mass and initially at rest. Immediately after the collision ball B moves forward at6.6 m/s . v PartA What fraction of the initial kinetic energy is lost in the collision? Express your answer using two significant figures.
