Question

# A race car enters a flat 200 m radius curve at a speed of 20 m/swhile increasing its speed at a constant 2 m/s2. If the coefficient of static friction is .700, what will the speed of thecar be when the car beings to slide? A) 24.3 m/s B) 31.5 m/s C) 37.1 m/s D) 36.2 m/s E) 28.7 m/s

A) 24.3 m/s
B) 31.5 m/s
C) 37.1 m/s
D) 36.2 m/s
E) 28.7 m/s

$$\displaystyle{\frac{{{m}{v}^{{2}}}}{{{r}}}}=?{m}{g}$$
$$\displaystyle{v}=?{\left(?{r}{g}\right)}$$
$$\displaystyle=?{\left({0.7}\times{200}\times{9.8}\right)}`{31}\frac{{m}}{{s}}$$
