A body of mass m, accelerates uniformly from rest to `v_(1)` in time `t_(1)`. The instantaneous power delivered to the body as a function of time is :

Options

A. `(mv^2)/(T^2).t`
B. `(mv^2)/(T^2)`
C. `(1)/(2)(mv^2)/(T^2).t`
D. `(1)/(2)(mv^2)/(T^2)`

Answer

a

Explanation

Instantaneous power is given as
`P=Fv=mav=m(v/T)(v/Tt)=(mv^2)/(T^2)t`
