The coefficient of friction between the tyres and road is 0.4. The minimum distance covered before attaining a speed of 8 `ms^(-1)` starting from rest is nearly (take, g=10 `ms^(-2)`)

A particle of mass 0.1kg has an iniital speed of 4ms^(-1) at a point A on a roudh horizontal road. The coefficient of friction between the object and road is 0.15. The particle moves to a point B at a distance of 2m from A. What is the speed of particle at B ? Take g=10ms^(-2)

The coefficient of friction between the tyres and the road is 0.1. The maximum speed with which a cyclist can take a circular turn of radius 3 m without skidding is ("Take g"=10ms^(-2))

The coefficient of friction between the tyres and the road is 0.1. The maximum speed with which a cyclist can take a circular turn of radius 3 m without skidding is ("Take g"=10ms^(-2))

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 (assume g = 10 ms^(-2) )
