A person brings a mass of 1 kg from the infinity to a point A. Initially the mass was at rest but it moves at a speed of 2ms-1 as it reaches A. The work done by the person on the mass is -3 J. The potential at A is
The total work done is the sum of kinetic energy and the potential energy of the body. Here, the total work done, ![]()
Let the kinetic energy be K.E and the potential at A be V. Given, mass of the body,
and speed, ![]()
