1. The problem statement, all variables and given/known data Car, mass 1000kg, accelerates from rest in straight line using constant mechanical power of 60kW. What is speed and acceleration after 5s. 2. Relevant equations W = Kf - Ki P= dE/dt 3. The attempt at a solution I've already worked out that the speed will be 24.5m/s. What I'm really wondering is if a constant mechanical power results in a constant acceleration. Any help would be appreciated. Thanks.
