0.364 kg toy car is powered by two C cells (3.00 V total) connected directly to a small DC motor. The car has an effective energy conversion efficiency of 52.6%, meaning that 52.6% of the electric energy applied to the motor is converted into translational kinetic energy. After 6.42 s, the car, which is initially at rest, reaches a speed of 3.43 m/s. What is the average current supplied to the car's motor?
