A seasoned mini golfer is trying to make par on a tricky number five hole. The golfer can complete the hole by hitting the ball from the flat section it lays on, up a 45° ramp, over a moat, and into the hole which is d = 2.35 m away from the end of the ramp. If the opening of the hole and the end of the ramp are at the same height, y = 0.970 m, at what speed must the golfer hit the ball
