A car travels around an unbanked curve of radius 300 m at a

speed of 35 m/s. Find the minimum value of thecoefficient of

static friction if no skidding occurs.

radius R = 300 m

speed v = 35 m/ s

we know v = [ R g ]

from this the minimum value of the coefficient of static friction if no skidding occurs is = v ^ 2 / Rg

= 0.41666
