Question:
The force that accelerates a car along a flat road is the frictional force exerted by the road on the car's tires.
(a) Explain why the acceleration can be greater when the wheels do not spin.
(b) If a car is to accelerate from 0 to 90 km/h in 12 s at constant acceleration, what is the minimum coefficient of friction needed between the road and tires? Assume that half the weight of the car is supported by the drive wheels.
Step by Step Answer:
a s k therefore f is greater if the wheels do not ...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
