Question

Find the maximum speed at which a car can take turn round a curve of 30 cm radius on a level road if the coefficient of friction between the tyres and the road is 0.4. Take `g = 10 ms^(-2)`.

Answer 1

Given,`mu=0.4,r=30m,g=10ms^(-2)`
Maximum speed `v_("max")=sqrt(mugr)`
`rArr" "v_("max")=sqrt(0.4xx30xx10)~~11ms^(-1)`
