You throw a basketball straight up into the air with an initial velocity of 5.6 m/s. The ball leaves your hand 1.2 meters above the ground. It moves upwards, stops, and then goes all the way down until it hits the ground (below the height you threw from).A. Use conservation of energy (and not the kinematics equations) to calculate the velocity of the ball the instant before it hits the ground.
