An unbanked circular highway curve on level ground makes aturn
tino4ka555 [31]

Answer:

Explanation:

Given

Velocity of traffic v=60\ mi/hr\approx 26.82\ m/s

Maximum value of Centripetal force is one-tenth of weight

such that (F_c)_{max}=\frac{mg}{10}

to make a safe turn centripetal force with radius of curvature r is given by

F_c=\frac{mv^2}{r}

(F_c)_{max}=\frac{mg}{10}=F_c=\frac{mv^2}{r}

\frac{mg}{10}=\frac{mv^2}{r}

r=\frac{10v^2}{g}

r=\frac{10\times 26.82^2}{9.8}

r=733.99\approx 734\ m
