Determine the maximum (constant) speed at which a 3.0 x 10^3 kg car can safely round a circular curve of radius 50. m on a horizontal road if the friction between the tires and the road is 20600 N. Sketch a picture and show all of your work.

3x10^3=3000kg Ff=Fc Ff=20600N R=50
20600=m(v^2/r)
20600=3000 (v^2/50)
-3000 -3000
17600=(v^2/50)
17600/50=(v^2/50)
352=(v^2)
now we square 352 to get rid of the power
v=18.76
(if multiple choice answer to nearest number)
20600=m(v^2/r)
