A 0.30 kg puck, initially at rest on a frictionless horizontalsurface, is struck by a 0.20 kg puck that is initially moving alongthe x axis with a velocity of 1.9m/s. After the collision, the 0.20 kg puck has a speed of0.5 m/s at an angle of θ =53° to the positive x axis.
(a) Determine the velocity of the 0.30 kg puckafter the collision.
(b) Find the fraction of kinetic energy lost in the collision.
