Question

Example 11.6 An object of mass 12 kg is at a certain height above the ground. If the potential energy of the object is 480 J, find the height at which the object is with respect to the ground. Given, g = 10 m s-2.​

Answer 1

Answer:

Potential Energy = mgh

Mass of object, m = 12 kg

g = 10 m/s²

Potential Energy = 480 J

Now,

480 = 12 × 10 × h

h = 4 m

Height at which the object is standing with respect to the ground is 4 m.
