Question

A seasoned mini golfer is trying to make par on a tricky hole #7. The golfer must complete the hole by getting the ball from the flat section it begins on, up a 50.5° ramp, and launching the ball over a gap and into the hole which is d = 1.15 m away from the end of the ramp. If the opening of the hole and the top of the ramp are at the same height, h = 0.910 m, at what speed v1 must the ball be moving as it approaches the ramp to land directly in the hole? Assume that the ball rolls without slipping on all surfaces, and once the ball launches off the incline, its angular speed remains constant. The acceleration due to gravity is 9.81 m/s2.
