Question

A body of mass 1 kg falls from a height of 5 m
How much energy does it possess at any instant?
(Take g = 9.8 m s?​

Answer 1

Answer:

39J

Explanation:

m = 1 kg , height = 5m and g = 9.8m/s^2

We know that total energy of a body is always constant according to the principle of conservation of energy.

So, energy possessed by the body at any instant = initial potential energy of the body= mgh

             = 1 * 9.8 * 5

              =   39 J
