Acar traveling on a flat (unbanked) circular track accelerates uniformly from rest with a tangential acceleration of 1.7 m/s^2. the car makes it one-quarter of the way around the circle before it skids off the track. from these data, determine the coefficeint of static friction between the car and the track

The coefficient of static friction between the car and the track

u=0.572

Explanation:

We don't know the mass of the car or any other information so the acceleration is the reason to solve the friction coefficient

∑

As we know

Also the center ward direction forces

But now vt relation with the tangential acceleration

replacing

So magnitude of the force can get by

Get the factor to simplify

Solve to u'
