Question

The sports car is rounding a flat, unbanked curve with radius R. If the coefficient of staticfriction between tires and road is us, what is the maximum speed vmax at which the drivercan take the curve without sliding?​

Answer 1

Answer:

the maximum speed of the should be

vmax= under root usgr

Answer 2

Answer:

the maximum speed with which driver can turn car is $\sqrt{urg}$.

Explanation:

Refer the figure attached below,

Normal force=weight

F(N)=mg

Centripetal force=friction

⇒ $\frac{mv^{2} }{r} =f$

⇒ $\frac{mv^{2} }{r}$=μF(N)

⇒ $\frac{mv^{2} }{r}$=μmg

⇒ $v=\sqrt{urg}$

Hence, the maximum speed with which car can turn is $\sqrt{urg}$.
