Question: A golfer hits a shot to a green that is elevated 3.40 m above the point where the ball is struck. The ball leaves the club at a speed of 18.4 m/s at an angle of 36.0 degree above the horizontal. It rises to its maximum height and then falls down to the green.
Part A: Ignoring air resistance, find the speed of the ball just before it lands.
I need help to find the speed of the ball just before it lands.
