A constant power P is applied to a car starting from rest. If v is the velocity of the car at time t, then:

A

`vpropt`

B

`vprop(1)/(t)`

C

`vpropsqrt(t)`

D

`vprop(1)/(sqrt(t))`

Text Solution

Verified by Experts

The correct Answer is:
B
`P=Fxxv` where v is velocity
`v=(x)/(t)`
`therefore vprop(1)/(t)`
