Answer: 0.5 m
Explanation:
Energy possessed by a body due its height above the surface of earth is known as gravitational potential energy.
Gravitation potential energy is given by:
G.P.E. = m g h
where m is the mass, g is the acceleration due to gravity and h is the height.
Given:
G.P.E. = 73.7 J
m = 15 kg
g = 9.8 m/s²
⇒ 73.7 J = 15 kg × 9.8 m/s² × h
⇒ h = (73.7 J) / ( 15 kg × 9.8 m/s²) = 0.5 m
