Physics

To calculate the average power delivered by the person throwing the ball, we need to determine the work done and then calculate power using the formula , where is the energy (work) and is the time.

 

Calculate the initial kinetic energy of the ball

Since the ball is thrown vertically upwards, the energy imparted is in the form of kinetic energy. The formula for kinetic energy is:

Where:

is the mass of the ball,

is the initial velocity.

 

Substitute the values:
