A body of mass m accelerates uniformly from rest to `v_1` in time `v_2`. As a function of time t, the instantaneous power delivered to the body is

A

`(mv_1t)/(t_1)`

B

`(mv_1^2t)/(t_1)`

C

`(mv_1t^2)/(t_1)`

D

`(mv_1^2t)/(t_1^2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`P=vecFvecv=maxxat=ma^2t`
`=m((v_1)/(t_1))t=(mv_1^2t)/(t_1^2)`
