A seasoned mini golfer is trying to make par on a tricky hole #5. The golfer can complete the hole by hitting the ball from the flat section it lays on, up a 45° ramp launching the ball into the hole which is d = 2.20 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 = 0.710 m, at what speed must the golfer hit the ball to land the ball in the hole? Assume a frictionless surface and the acceleration due to gravity is 9.81 m/s2.
