## Homework Statement

A 13500 N car traveling at 50.0 km/h rounds a curve of radius 2.00x10^2 m. Find the following:

a). The centripetal acceleration of the car.

b). The force that maintains centripetal acceleration

c). the minmum coefficient of static friction between the tires and the road that will allow the car to round the curve safely.

## Homework Equations

a). ac=vt^2/r

b) i think i would use: Fc=mvt^2/r but I am unsure.

c) i do not know this equation.

## The Attempt at a Solution

For a). I have: 14^2/200=0.965

for b). I know the answer is 1.33x10^3 but Im still having difficulties trying to solve this.

for c) I know the answer is 0.0985 but I still have to figure out b). first. Please help me, any help is greatly appreciated. Thanks.
