5. You throw a ball of mass m straight up with initial speed vo. (a) What would be the maximum height of the ball if there were no drag force on the ball? (b) Is the drag force a conservative force? Suppose the ball reaches a maximum height that is 80% of the value you found in (a) due to the drag force. With this information, (c) Derive an upper and lower bound on the speed at which the ball will strike the ground. Explain your reasoning! Hint: for the upper bound, pretend there is no drag force on the way down. (d) Explain why the actual speed at which the ball will strike the ground is neither exactly the upper nor lower bound you found in (c).
