A hockey puck B rests on a smooth surface of ice and is struck by asecond puck A , which was originally traveling at 40.0 {\rm m}/{\rms} and which is deflected 30.0^\circ from its original direction.(See the figure below .) Puck B acquires a velocity at a 45.0^\circ{\rm angle} to the original direction of A . The pucks have thesame mass.
Compute the speed of puck A after the collision.Compute the speedof puck B after the collision.What fraction of the original kineticenergy of puck A dissipates during the collision?
