A 0.246-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 36.1%, meaning that 36.1% of the electric energy applied to the motor is converted into translational kinetic energy. After 4.96 seconds, the car, which is initially at rest, reaches a speed of 1.81 m/s. What is the average current supplied to the car\'s motor?
