A radio controlled model car with mass m=4.58 kg starts a race initially from rest at t=0 and accelerates with constant acceleration to a speed of 11.2 m/s in a time of t=6.6 s. What is the average power do the car's batteries have to deliver during the acceleration, and what is the instantaneous power at the end of the time interval? Select one answer for average power (P-ave) and one for the instantaneous power at t=6.6 s (P-final).
