Question

A body of mass 5kg falls from a height of 5m . How much energy does it possess at any instant

Answer 1

potential energy= MGH(mass* gravity* hight)
= 5*10* 5
= 250 joule
at any instance this potential energy is converted into kinetic energy in this type of motion

Answer 2

The energy possessed by a body at any instant is 245 Joules.

Explanation:

Given that,

Mass of the body, m = 5 kg

It is falls from a height of 5 m, h = 5 m

To find,

The energy possessed by a body at any instant.

Solution,

When an object is lifted to a height, it possess potential energy. It is given by :

$P=mgh$

$P=5\ kg\times 9.8\ m/s^2\times 5\ m$

P = 245 Joules

So, the energy possessed by a body at any instant is 245 Joules.
