A 0.30-kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.20-kg puck that is initially moving along the x-axis with a velocity of 7.7 m/s. After the collision, the 0.20-kg puck has a speed of 4.6 m/s at an angle of
θ = 53°
to the positivex-axis.
(a) Determine the velocity of the 0.30-kg puck after the collision.
magnitude m/s
direction ° from the positive x-axis
(b) Find the fraction of kinetic energy lost in the collision.
