1. The problem statement, all variables and given/known data A certain amount of work Wo is required to accelerate a car from rest to a speed v. How much work is required to accelerate the car from rest to v/2? 2. Relevant equations W = Fd 3. The attempt at a solution I know that if we were finding the distance instead of velocity, then the answer would be Wo/2, but I'm not sure if the force is the same for each situation. If it is, then I assume that the answer would also be Wo/2.
