Question

A 14.0 Kg ball is dropped from a building, the building has aheight of 255 m. What is the Potential energy of the ball?

Answer 1

Given data

*The given mass of the ball is m = 14.0 kg

*The given height is h = 255 m

*The value of the acceleration due to gravity is g = 9.8 m/s^2

The formula for the potential energy of the ball is given as

$U_p=mgh$

Substitute the known values in the above expression as

$\begin{gathered} U_p=(14.0)(9.8)(255) \\ =34986\text{ J} \end{gathered}$

Hence, the potential energy of the ball is 34986 J
