(20%) Problem 4: A 6.25-kg bowling ball moving at 9.85 m/'s collides with a 0.85-kg bowling pin, which is scattered at an angle of 0 = 21 from the initial direction of the bowling ball, with a speed of 10.5 m/s. CA 50% Part (a) Calculate the direction, in degrees, of the final velocity of the bowling ball. This angle should be measured in the same way that 0 is.
