Question

a person can jump 12m high on the surface of the moon.calculate the heightthat he can jump on the surface on the earth

Answer 1

Explanation:

Since the gravitational force on the Moon is 1/6 of the gravitational force of Earth , the person can jump upto a height of -

1/6×12=2m on the surface of the Earth.

Answer 2

A person can jump on the surface of the earth to the height of 2m.

Given:

The person can jump 12 m high on the surface of the moon.

To Find:

The height that he can jump on the surface on the earth.

Solution:

The energy required by a man to jump up to a height h is given by E = W = mgh = mg'h'

gh= g/6×12 [ The acceleration due to gravity on the moon's surface is 1/6th of the acceleration due to gravity on the earth's surface]

h= 2

Hence, the person can jump on the surface of the earth to the height of 2m.
