Answer:
E = 73.5 J
Step-by-step explanation:
Given that,
Mass of a football, m = 0.5 kg
It is kicked 15 m into the air, h = 15 m
We need to find the gravitational potential energy of the ball.
We know that the formula for the gravitational potential energy is given by :
E = mgh
g is the acceleration due to gravity
Substituting all the values in the above formula.
E = 0.5 kg× 9.8 m/s² × 15 m
= 73.5 J
So, the gravitational potential energy of the ball is 73.5 J.
