a hockey puck B resting on a smooth surface is struck by a second puck A which was orginally traveling at 50 m/s. After colliding, the speed of puck A us reduced to 35 m/s and is deflected through an angle a from its orginial velocity of A. Assume that the two pucks have the same mass e and that the collision is not perfectly elastic
