A batter hits a baseball with mass 0.150 kg straight upward with an initial speed of 28.0 m/s

How much work has gravity done on the baseball when it reaches a height of 26.0 m above the bat?

Use the work-energy theorem to calculate the speed of the baseball at a height of 26.0 m above the bat. You can ignore air resistance.

Does the answer to part B depend on whether the baseball is moving upward or downward at a height of 26.0 m ?
