A 0.954 kg toy car is powered by four AA batteries (6.00 V total) 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 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?
