The sports car has a mass of 2.3 Mg, and while it is traveling at 28 m/s the driver causes it to accelerate at 5 m/s2. If the drag resistance on the car due to the wind is FD = (0.3v2) N, where v is the velocity in m/s, determine the power supplied to the engine at this instant. The engine has a running efficiency of ε = 0.68.
