The coefficent of friction between tyers and road is 0.5. The maximum speed (in m/s) with which a car be driven round a curve a radius of 20m without skidding is [ g = 10m/s2]

Skidding of Vehicle on a Level Road -
Frictional force Req. centripetal Force
Safe vector move
r = radius of the curve
coefficient of friction
is the maximum velocity by which vehicle can turn on a circular path of radius r.
So,
