Question

an object of mass 12 kg is at a certain height above the ground if the potential energy of the object is 480 j fi d the height at which the object is with respect to the ground given g= 10 m/second square​

Answer 1

Answer:

mass of the object , m= 12 kg

potential energy Ep= 480 j

but Ep = Mgh

therefore 489= 12×10× h

or h= 480/129 = 4m

Answer 2

Answer:

4m.

Explanation:

Mass of the object,m=12kg.

Potential energy,Ep=480j.

But,Ep=mgh

therefore, 480=12×10×h

= 4m.

the object is at a height of 4m.

Hope it helps.
