A hockey puck Brests on a smooth surface of ice and is struck by a second puck A, which was originally traveling at = 40.0m/s (East)and which is deflected = 28.0 deg(NE)from its original direction. (See the figure below .) Puck B acquires a velocity at a = 46.0deg to the original direction of A. The pucks have the same mass.

Compute the speed of puck after the collision. = m/s
