A 0.302 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.177 kg puck moving initially along the x axis with a speed of 2.38 m/s. After the collision, the 0.177 kg puck has a speed of 1.38 m/s at an angle of 27? to the positive x axis. Determine the velocity of the 0.302 kg puck after the collision.
