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. 2,058 j

B. 5,488 j

C. 560 j

D. 3,430 j

Answer 1

Potential energy = (mass) · (gravity) · (height above the reference level)

Potential energy = (70 kg) · (9.8 m/s²) · (8 m)

Potential energy = 5,488 kg-m²/s²

Potential energy = 5,488 joules

Answer 2

Answer:

B. 5,488 j
