Question:

As the driver steps on the gas pedal, a car of mass 1 160 kg accelerates from rest. During the first few seconds of motion, the car’s acceleration increases with time according to the expression
a = (1.16 m/s3) t ─ (0.210 m/s4) t2 + (0.240 m/s5) t3
(a) What work is done by the wheels on the car during the interval from t = 0 to t = 2.50 s? (b) What is the output power of the wheels at the instant t = 2.50 s?
