Question

Calculate the potential energy of a 4 kg cat crouched 3 meters off the ground

Answer 1

Answer : Potential energy of the cat is 117.6 J.

Explanation :

It is given that,

Mass of the cat, m = 4 kg

Height from the ground, h = 3 m

We know that the potential energy of the cat is possessed by the virtue of its height under the action of gravity.

Mathematically, it is given as :

$PE=mgh$

$PE=4\ kg\times 9.8\ m/s^2\times 3\ m$

$PE=117.6\ J$

Hence, this is the required solution          

Answer 2

Gravitational potential energy = mass × gravity × height

Ep = (4)(9.81)(3)

Energy = 117.72 Joules

= 1.2x10^2 Joules
