A 0.283 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.108 kg puck moving initially along the x axis with a speed of 2.37 m/s. After the collision, the 0.108 kg puck has a speed of 1.37 m/s at an angle of 32◦ to the positive x axis.

a. Determine the velocity of the 0.283 kg puck after the collision.

b. Find the fraction F of kinetic energy lost in the collision.
