Physics

To calculate the average power of the work done by gravity, we follow these steps:

 

Calculate the work done by gravity

The work done by gravity is equal to the change in gravitational potential energy, which can be calculated as:

Where:

is the force due to gravity acting on the ball,

is the mass of the ball,

is the acceleration due to gravity,

is the distance the ball falls.

 

First, calculate the force due to gravity:

Next, calculate the distance the ball falls. The distance can be found using the kinematic equation for an object in free fall from rest:

Where:
