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_(1)t)/(t_(1))`

B

`(mv_(1)^(2)t)/(t_(1))`

C

`(mv_(1)t^(2))/(t_(1))`

D

`(mv_(1)^(2)t)/(t_(1)^(2))`

Text Solution

Verified by Experts

The correct Answer is:
D
Power (P) `= vec(F).vec(v) = FV ma v= ma^(2)t= (mv_(1)^(2)t)/(t_(1)^(2))`
