The energy that the man has gained in being lifted is 3000J which is in the form of potential energy.
Explanation:
Given:
Work done, W = 3000J
Height, h = 2.5m
Time, t = 0.4 seconds
Energy gained = ?
As the man gets lifted, it gains potential energy.
Potential energy will be equal to the work done by the elevator.
We know,
potential energy = mgh
Thus, the energy that the man has gained in being lifted is 3000J which is in the form of potential energy.
