Question

A boy located at point A halfway between the center O of the semicircular wall and the wall itself throws a ball at the wall in a direction forming an angle of 45 degrees with OA. Knowing that after hitting the wall the ball rebounds in a direction parallel to OA, determine the coefficient of restitution between the ball and the wall.
