Find the maximum speed with which an automobile can make a circular curve of radius $8 m$ without slipping if the road is unbanked and the coefficient of friction between the road and the tyres is $0.8$ . $(g = 10 m s^{- 2})$

Options:

Answer:

Solution:

Here centripetal force is provided by the force of friction.

$∵ f = μ_{s} N$

$∴ f = \frac{{mv}^{2}}{r}$

$μ_{s} N = \frac{{mv}^{2}}{r} or μ_{s} mg = \frac{{mv}^{2}}{r}$

$∴ v = \sqrt{μ gr} = \sqrt{0.8 \times 10 \times 8} = 8 m s^{- 1}$
