= 2. A ball bounces on the 30° inclined plane such that it rebounds perpendicular to the incline with a velocity of VA 40 ft/s. Determine the distance R to where it strikes the plane at B. Please use the coordinate system as shown in the problem figure. You must show the complete derivation for all equations used for your calculations, starting with the fundamental differential relationships. y B 30° X R =40 ft/s A
