1. The problem statement, all variables and given/known data A) A car moving at 18 m/s is accelerated to 35 m/s. If the change in kinetic energy is 154 kJ, determine the mass of the car. 2. Relevant equations KE = 0.5mv^2 Kinetic energy = change in momentum = mv2-mv1 3. The attempt at a solution Im not sure how to go about this problem, but I suspect that the mass can be obtained from the fact that kinetic energy is equal to the change in momentum?
