A 0.482-kg toy car is powered by one D cell (1.50 V) connected directly to a small DC motor. The car has an effective energy conversion efficiency of 47.1%, meaning that 47.1% of the electric energy applied to the motor is converted into translational kinetic energy. After 7.15 seconds, the car, which is initially at rest, reaches a speed of 2.89 m/s. What is the average current supplied to the car\'s motor.
