Ojo stands 30m from a wall and lewis stands 10m from the same wall. If ojo throws a ball at an angle of 450 above the horizontal, and it collides elastically with the wall. How fast does he need to throw the ball so that lewis will catch it? consider ojo and lewis to be the same height, and both are on the same perpendicular line from the wall.
