Question

A 25kg box is suspended on a rope 25m over the ground.

Calculate the magnitude of Potential Energy between the box and Earth.

A. 625 J

B. 245 J

C. 6125 J

D. 9.8 m/s2

Answer 1

Answer:

Explanation:

PE = mgh where m is the mass of the object, g is the gravitational pull on the object (always 9.8!), and h is the height of the object in meters.

PE = 25(9.8)(25) so

PE = 6125 J, choice C.
