Question

An object of mass 12kg is at a certain height from tye ground . if its potential energy is 480J , then find its height with reference to the ground . ( take g =10 m s^2.)
​

Answer 1

Hey friend!!

Here is your answer...

⬇️⬇️⬇️⬇️⬇️⬇️

Mass =12kg

g=10m/s^2

h=?

$potential \: energy = mgh \\ 480 = 12 \times 10 \times h \\ h = \frac{480}{12 \times 10} \\ h = 4m$

HOPE that it will help you ✌️ ✌️

Answer 2

ANSWER :

Mass = 12 kg

Potential Energy = 480 J

Acceleration due to gravity = 10m/s^2

Potential Energy = m x g x h

=> 480 = 12 x 10 x h

=> 480 = 120 x h

=> h = 480/120 = 4 m

Therefore, height of the object is 4m with reference to the ground.

Hope this helps you mate ☺☺
