Question

An object with a mass of 70 kilograms is supported at a height 8 meters above the ground. What's the potential energy of the object with respect to the ground?

A. 560 J
B. 5,488 J
C. 2,058 J
D. 3,430 J

Answer 1

Answer:

b ) 5,488J

Explanation:

As equation of potential energy

= mgh

here,

mass(m) =70kg

gravitational force (g)= 9.8 m/ s^2

height ( h) = 8 m

Now,

pE = 70× 9.8×8 J

=5,488J
