Answer:

Height reached by the object is 4 m.

Explanation:

Given,

Mass of object = m =  12 kg

Acceleration due to gravity = g = 10 m/s^2

Potential Energy of object = 480 J

To find: Height reached by object.

Solution:

Concept: The energy possessed by body by virtue of its position and configuration is known as Potential Energy.

So, Potential Energy = mass*acceleration*height

or, P.E = mgh

here, m = 12 kg , g = 10m/s^2 , P.E = 480 J

Substituting the values,

480 = 12 * 10 * h

or, h= 480 / 120

or, h = 4 m

Therefore, Height reached by the object is 4 m.
