An object of mass m, initially at rest under the action of a constant force F attains a velocity v in time t. Then, the average power supplied to mass is

A

`(mv^(2))/(2t)`

B

`(Fv)/(2)`

C

Both are correct

D

Both are wrong

Text Solution

Verified by Experts

The correct Answer is:
C

(c ) `:. "Average power" =(W)/(t)=(KE)/(t)=(mv^(2))/(2t)`
`rArr" "P=(F((1)/(2)at^(2)))/(t=(1)/(2)Fv)`
