Question

An object of mass 40 kg is raised to a height of 5 m above the ground. What is its potential energy?

Answer 1

Answer:

If the object is allowed to fall, find its kinetic energy when it is half-way down.

∴ W = 40 × 9.8 × 5 = 1960 J.

At half-way down, the potential energy of the object will be 1960 / 2 = 980 J.

Answer 2

Answer:

K.E = m × g × h

Where,

m = Mass of the object

h = Vertical displacement

g = Acceleration due to gravity  (9.8 ms-2)

P.E = 40 × 9.8 × 5

P.E = 1960 J
