Physics

To calculate the work done by gravity when the ball reaches its maximum height, we can use the fact that gravity does negative work in the upward direction, as it opposes the motion of the ball.

 

First, let's calculate the maximum height the ball reaches. We can use the kinematic equation for motion under constant acceleration:

 

Where:

(velocity at the maximum height),

(initial velocity),

(acceleration due to gravity, acting downward),

is the maximum height (displacement).

 

Solve for the maximum height
