## Homework Statement

3. A 1500 kg car is moving on an un-banked curve with a radius of 98 m. The coefficients of static and kinetic friction are 0.73 and 0.50 respectively. The maximum speed the car can move without skidding is:

*a. 27 m/s

b. 22.4m/s

c. 21 m/s

d. 30 m/s

e. none of the above

## Homework Equations

Fn*μ=mv

^{2}/r

## The Attempt at a Solution

I used that formula with the coefficient of kinetic friction (because the object is in motion when it has velocity) and I got 21.9...the answer key says its 27.
