1. The problem statement, all variables and given/known data As the driver steps on the gas pedal, a car of mass 1100 kg accelerates from rest. During the first few seconds of motion, the car's acceleration increases with time according to the expression below. a = (1.160 m/s^3)t - (0.210 m/s^4)t^2 + (0.240 m/s^5)t^3 (a) What work is done on the car by the wheels during the interval from t = 0 to t = 3.00 s? ____________ J (b) What is the wheels' output power at the instant t = 3.00 s? ___________ W 3. The attempt at a solution Im really quite confused about this one... Although it seems like a problem where derivatives might be involved to simplify this a little more. Am I on the right track at all? Please Help??
