physics question and need the explanation and answer to help me learn.
Grace is playing soccer and kicks a ball off of the goal post. Before hitting the goal post, the ball was travelling at 39 ft/s at an angle of 28 degrees from the goal line. After hitting the goal post, the ball travels at an angle of 17 degrees from the goal line. Determine the coefficient of restitution between the ball and the goal post.
