The coefficient of friction between the rubber tyres and the road wayis $0.25.$ The maximum speed with which a car can be driven round a curve of radius $20 m$ without skidding is $(g = 9.8 m / s^{2})$

Options:

Answer:

Solution:

$μ mg = mv^{2} / r$ or $v = μ gr$ or $v = (0.25 \times 9.8 \times 20) = 7 m / s$
