Consider the following statements. A and B and identify the correct answer given below. I. Body initially at rest is acted upon by a constant force. The rate of change of its kinetic energy varies linearly with time. II. When a body is at rest, it must be in equilibrium.

View answer and explanation

Correct option: C

A is correct and B is wrong

Option C is correct because the rate of change of kinetic energy is proportional to time when a constant force acts, and a body at rest is not necessarily in equilibrium (e.g., on an inclined plane).

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
