A body is initially at rest. It undergoes one-dimensional motion with constant acceleration. The power delivered to it at time t is proportional to

A

`t^(1//2)`

B

`t`

C

`t^(3//2)`

D

`t^2`

Text Solution

Verified by Experts

The correct Answer is:
B
We know that, Power `P = F xx v`
`P = ma xx at " " [because v = u + at = at ("Here" u = 0)]`
`P= ma xx at`
As m and a are constant. `therefore P prop i` So option (b) is correct.
