Homework Statement
A car has an engine which delivers a constant power. It accelerates from rest at time t = 0, and at t = t0 its acceleration is a0. What is its acceleration at t = 2t0? Ignore energy loss due to friction.
Homework Equations
P=W/t, W=Fd, F=ma
The Attempt at a Solution
substitute the last two equations into the first equation to get P=m*a*d/t=constant. m is always constant, so a*d/t = constant. I don't know what to do from here.
