You are driving down the dark, winding Northwest Georgia two-lane road at a speed of 34 miles per hour. You are driving due north when you come upon perfectly flat, circular curve. Exactly one-tenth of a mile along the curve later, you are driving due west If the car has a mass of 2308 kg, what is the force of friction holding the car on the road (in Newtons)? (Hint: make sure all units are converted appropriately; you will need to find the

*radius* of the curve.) (Double hint: If you highlight this parenthetical clause, you will find that the curve has a radius of *

102* m.

That is the question I was given. the number between the **'s is 102.

so my velocity is 34 mi/h, converted to m/s is 15.2

my mass is 2308 kg

and my radius is 102 m

the length of the curve, if important, is 320 m

i was trying to use the equation F= m(v^2/r)

but i get 5227.8, and that answer is incorrect

if you could even tell me what equation to use I would be so grateful!
