A 0.391 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.228 kg puck moving initially along the x axis with a speed of 2.96 m/s. After the collision, the 0.228 kg puck has a speed of 1.96 m/s at an angle of 26 to the positive x axis. Determine the velocity of the 0.391 kg puck after the collision.
