A body is initially at rest. It undergoes one-dimensional motion with constant acceleration. The power delivered to it at time is proportional to
(i)
(ii)
(iii)
(iv)

Let the body mass be

Let the Acceleration be

According to Newton’s second law of motion, we have,

constant

As, constant

constant

On integrating we get,

Where, is a constant

The relation of power is given by:

From equation

Thus, we can say that power is proportional to time.
