A bend in a level road has a radius of 100 m Find the maximum speed which a car turning this bend may have without skidding if coefficient of friction between the tyres and the road is 0 .8 S .

Text Solution

Verified by Experts

`r = 100 m , upsilon = ? , mu_(s) = 0.8 `
As ` upsilon = sqrt( mu_(s) r g ) :. upsilon = sqrt( 0.8 xx 100 xx 9.8 ) = 28 ms^(-1) ` .
