A 0.228 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 2.27 m/s. After the collision, the 0.228 kg puck has a speed of 1.27 m/s at an angle of 31◦ to the positive x axis. Determine the magnitude of the velocity of the 0.228 kg puck after the collision. Answer in units of m/s.
