(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A car of mass m has an engine which can deliver power P. What is the minimum time in which the car can be accelerated from rest to a speed v?

2. The attempt at a solution

P = W/t

(W is work done, t is time)

F = ma

So,

P = Fs/t

(F is force, s is distance)

P = mas/t

Making t as the subject,

t = mas/P

t = mv^{2}/P

Is there any thing wrong with my final equation?
