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. `vprop t`B. `v prop (1)/(t)`C. `v prop sqrt(t)`D. `v prop (1)/sqrt(t)`

Answer» [3]
Power, `P=mxxaxxv`
`P=mxx(v^(2))/(t)`
If p is constant, then for a given body `v^(2)propt`
or `vprop sqrt(t)`
