Answer:
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'
