SUMMARY
The horizontal force exerted by the wheels of a toy car can be calculated using Newton's 2nd law, given the acceleration and the coefficient of friction. With a coefficient of friction of 0.62 and an acceleration of 0.40056 m/s², the normal force is essential for determining the frictional force. Although the mass of the car is unknown, the torque of the motor (0.0382 Nm) and the wheel size (85 mm diameter) provide additional context for calculating the force. The motor drives one rear wheel, which influences the overall dynamics of the toy car.
