A 0.30-kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.20-kg puck that is initially moving along the x-axis with a velocity of7.1 m/s. After the collision, the 0.20-kg puck has a speed of 1.8 m/s at an angle of ? = 53° to the positive x-axis.

(a) Determine the velocity of the 0.30-kg puck after the collision.
