A ball with a potential energy of 7500 J is at the top of a hill. The ball weighs 500 N, what is the height of the ball?

A. 15 m
B. 8000 m
C. 3750000 m
D. 7000 m

height = 15 meters

Explanation:

here's the solution :-

potential energy =

( where, m = mass , g = acceleration due to gravity and h = height )

=》P.E. = weight × height

( because, weight ( gravitational force = m × g ))

=》7500 = 500 × height

=》height = 15 meters

the average speed is 24.57 km/hr
