Bus Circular Motion: Calculating Minimum Friction for Laptop Stability

[farhannaeem]

A bus passenger has her laptop sitting on the flat seat beside her as the bus, traveling 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.

 

[praharmitra]

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 I am trying to study for the assignments and the tests i missed
