1.	The coefficient of friction between the tyres and the road is 0.25. The maximum speed with which a car can be driven round a curve of radius 40 m without skidding is (Take g = 10 ms^(-2))
Answer» `40 ms^(-1)` `20 ms^(-1)` `15 ms^(-1)` `10 ms^(-1)` SOLUTION :Given :` R= 40m, mu = 0.25,g= 10ms^(-2)` ` thereforev_(max ) = sqrt(mu g r) = sqrt(0.25xx 10 xx 40) = 10ms^(-1)`
