Vedclass · Answer

(C) For a vehicle to move in a circular path of radius $r$ on a flat road, the necessary centripetal force is provided by the static friction between the tires and the road surface.Since the road is smooth (frictionless), the coefficient of friction $\mu = 0$.The maximum safe speed $v$ on a flat circular road is given by $v = \sqrt{\mu rg}$.Substituting $\mu = 0$, we get $v = \sqrt{0 \cdot rg} = 0$.Therefore, it is impossible for a vehicle to maintain a circular path on a perfectly smooth flat road at any non-zero speed.

What is the speed of a vehicle moving on a flat and smooth (frictionless) circular path of radius $r$?
