Agolfer hits a shot to a green that is elevated 3.20 m above the point where the ball is struck. the ball leaves the club at a speed of 18.1 m/s at an angle of 49.0° above the horizontal. it rises to its maximum height and then falls down to the green. ignoring air resistance, find the speed of the ball just before it lands.
