Find the energy possessed by an object of mass 10kg when it is at a height of 6m above the ground. Given `g=9.8ms^(-2)`.

Text Solution

Verified by Experts

Mass of the object `m=10kg`
Displacement (height) `h=6m`
Acceleration due to gravity `g=9.8ms^(-2)`
Potential energy = mgh
`=10kgxx9.8ms^(-2)xx6m`
`=588J`
The potential energy is 588 J.
