Question
A bend in a level road has a radius of 100m. find the maximum speed which a car turning this bend may have without skidding if the coefficient of friction between the tires and road is 0.8.

Solution
Maximum speed, which a car turning the bend may have without skidding, vmax = `sqrt(μrg)`
= `sqrt(0.8 xx 100 xx 9.8)`
= 28 m/s
