Question

A body of mass 4kg falls from a height of 15m. How much energy does it possess at
any instant? (g = 9.8 m/s2)​

Answer 1

Answer:

Explanation:

m=4 kg, h=15m, g=9.8$ms^{-2}$

 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= 4×9.8×15=588J
