It is friction that provides the force for a car to accelerate, so for high-performance cars the factor that limits acceleration isn't the engine; it's the tires. For the steps and strategies involved in solving a similar problem, you may view a Video Tutor Solution. Part A For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 50 mph? Suppose that μs = 1.00 and μ = 0.80. Express your answer with the appropriate units.

Question
**Understanding Friction and Acceleration**

Friction plays a critical role in automobile acceleration. Specifically, the force needed for a car to accelerate is provided by the friction between the tires and the road, which is often the limiting factor in a car's acceleration, rather than the engine capacity.

**Problem: Car Acceleration with Friction**

*Part A:* Determine the shortest time it takes for a car to accelerate from 0 to 50 mph. Assume the coefficient of static friction (\( \mu_s \)) is 1.00, and the coefficient of kinetic friction (\( \mu_k \)) is 0.80.

**Input Your Answer**

Use appropriate units to express your answer for \( \Delta t \) (change in time).

- **Input field:** \( \Delta t =\) [user input: 11.404] seconds
