A car drives around a curve with radius 390 m at a speed of 32 m/s. The road is not banked. The mass of the car is 1200 kg.
(a) What is the frictional force on the car?
I really don't know how to solve this could someone please help me out on this. Thank you.

If the road is not banked
the frictional force = centripetal force =
= m•v²/R = 1200•32²/390 = 3150 N
