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 = 1.45 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 = 0.820 m, at what speed must the golfer hit the ball to launch the ball over the moat so that it lands directly in the hole? Assume a frictionless surface, so the ball slides without rotating. The acceleration due to gravity is 9.81 m/s². m/s 45°
