The engine of a car, where properly geared, can cause its wheels to spin, but this can
only happen at low road speeds. How is this best explained?
The product of the output power and the speed of the car is greater than the
force of friction between the tyres and the road
The road friction divided by the car output power is greater than the speed of the
car
The ratio of output power to the engine torque is greater than the speed of the
car
The output power from a car engine is greater at lower road speeds
The product of the speed of the car and the output power is less than the force of
friction between the tyres and the road
The car output power divided by the speed of the car is greater than the force of
friction between tyres and the road
