In order to complete a tough “split” in bowling, a bowling ball of mass 6.5 KG is rolled with a velocity of 12 M/S. The ball hits a 1.3 KG bowling pin, sending it off with the speed of 3.5 M/S at an angle of 80° with respect to the original direction of the bowling ball. What is the angle and direction of the bowling balls velocity after the collision with the pin?
