# Circular motion of a bus

A bus passenger has her laptop sitting on the flat seat beside her as the bus, travelling at 10.0 m/s, goes around a turn with a radius of 25.0 m. what minimum coefficient of static friction in necessary to keep the laptop from sliding?

i am trying to get the steps on how to do this question. i can not think of a way to start this question.

Can you draw a FBD? If you can proceed. If not, I suggest you study that thoroughly before you attempt these questions

I will give you the necessary equations:

Centripetal Force $$F_{c} = \frac{mv^2}{r}$$

Frictional Force $$f = \mu_s N$$, where N is the normal force.

thanks ill try my best to finish it off
i was sick fro a couple of weeks
so i missed classes and now im trying to study for the assignments and the tests i missed

Ah! ok. Do ask if you have issues learning anything. We can help. And when you do solve this question, follow up on this post and show what you have done.
