6.95-kg bowling ball moving at 10.0 m/s collides with a 1.60-kg bowling pin, scattering it with a speed of 8.00 m/s and at an angle of 29.5° with respect to the initial direction of the bowling ball.
(a) Calculate the final velocity (magnitude and direction) of the bowling ball.
magnitude :
direction :
(b) Ignoring rotation, what was the original kinetic energy of the bowling ball before the collision?
(c) Ignoring rotation, what is the final kinetic energy of the system of the bowling ball and pin after the collision?
