Find μs of the car.(adsbygoogle = window.adsbygoogle || []).push({});

- A Car takes 10 seconds to accelerate to 80km before the driver shifts the car into neutral.

- The cars mass = 1810kg

- The car coats 0.9km before coming to a complete stop.

- The total time = 86 seconds.

Here is the work I have done.

μs = ma/mg

to find a

V2 = V1 +at

22.2 = 0 +a10

a = 2.22m/s2

μs = 1810 * 2.22 / 1810 * 9.8

μs = 0.22

Does this make sense. This is the μs for the road right? How can I find it for the car? I figure I need to use the total distance it travel for something but I'm not sure how. Any help is welcome

Thanks!
