A 0.300-kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.200-kg puck moving initially along the x axis with a speed of 2.00 m/s. After the collision, the 0.200-kg puck has a speed of 1.00 m/s at an angle of θ = 53.0° to the positive x axis.
(a) Determine the velocity of the 0.300-kg puck after the collision.
(b) Find the fraction of kinetic energy lost in the collision.
