### Physics Problem: Projectile Motion with Drag Force

#### Problem Statement:
You throw a ball of mass \( m \) straight up with initial speed \( v_0 \).

**(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).

---
In this problem, you are analyzing the motion of a ball thrown upward with an initial speed \( v_0 \) and considering the effects of drag force which opposes the motion. The scenario is assessed under two conditions: with and without the drag force, providing insight into the dynamics of projectile motion in a resisting medium.
