You throw a ball into the air. You let the ball go at a height of 1.5 m, and the ball is moving at a speed of 8 m/s when you let it go. The ball weighs 0.5 kg. a. What is the total energy of the ball when you let it go? b. Later, the ball is moving through the air at a speed of 4 m/s. How high is it off the ground? Assume energy is conserved.
