A flat (unbanked) curve on a highway has a radius of 260 m. A car rounds the curve at a speed of 18.0 m/s . What is the minimum coefficient of friction that will prevent sliding?
A= v2/R I got the acceleration but the problem does not give the mass for caluculating the normal force
The Attempt at a Solution
1.246 m/s is what I got for the acceleration after that I do not know what I should be doing.
