A 0.954-kg toy car is powered by three D cells (4.50 V total) connected directly to a small DC motor. The car has an effective energy conversion efficiency of 30.6%, meaning that 30.6% of the electric energy applied to the motor is converted into translational kinetic energy. After 6.42 seconds, the car, which is initially at rest, reaches a speed of 2.35 m/s. What is the average current supplied to the car\'s motor?
