Question

A) An object of mass 5 kg is placed at a height of 10m from the ground. What kind of energy does this object possess? Also find the amount of energy possessed by the object. (Take g= 9.8m/s2)

Answer 1

Answer:

It possesses potential energy.

Using P.E= mgh, where

m= mass

g= gravitational force (9.8 m/s²)

h= height

Given:

m= 5 kg.

g= 9.8 m/s²

h= 10 m.

Required: P.E.

Solution:

P.E.= mgh

= (5 kg)(9.8 m/s²)(10 m.)

= 490 kg m²/s² or J (Joule)

The answer is 490 J.
