A basketball of mass 0.624 kg is shot from a vertical height of 1.65 m and at a speed of 19.3 m/s. After reaching its maximum height, the ball moves into the hoop on its downward path, at 3.05 m above the ground. Using the principle of energy conservation, determine how fast the ball is moving just before it enters the hoop.
