A tennis ball of mass m is dropped from rest at point A, covering a height H, above a frictionless inclined plane at an angle 45 degrees to the horizontal as shown below. The moment the ball hits the inclined plane, it bounces horizontally at point B with the same speed with which it struck the plane and strikes the plane again at point C. In terms of g and H, determine the following quantities: a.) The speed of the ball just before it strikes the plane at point C.⁣ b.) The time the ball is in flight between points B and C⁣ c.) The distance L along the plane from point B to C.⁣
