A 0.50kg rubber ball is thrown into the air. At a height of 20m above the ground, it is traveling at 15m/s.

What is its gravitational potential energy relative to the ground?

$\tt{\huge{\blue{Explanation:}}}$

The gravitational potential energy of an object is given by

$\boxed{GPE = mgh}$

where:

GPE = gravitational potential energy

m = mass

g = acceleration due to gravity = 9.8 m/s²

h = height

$\tt{\huge{\red{Solution:}}}$

Solving for the gravitational potential energy

GPE = mgh

GPE = (0.50 kg)(9.8 m/s²)(20 m)

$\boxed{GPE = \text{98 J}}$

Therefore, the gravitational potential energy of the rubber ball is 98 J.
