For a banked curved road,if the velocity of the vehicle $v < v_0$ (where $v_0$ is the optimum speed),what is the direction of the frictional force?

How is centripetal force provided during motion on a level circular path?

If a cyclist moving with a speed of $4.9 \, m/s$ on a level road can take a sharp circular turn of radius $4 \, m$,then the coefficient of friction between the cycle tyres and the road is:

$A$ motorcyclist rides in a horizontal circle about a central vertical axis inside a cylindrical chamber of radius $r$. If the coefficient of friction between the tyres and the inner surface of the chamber is $\mu$,what is the minimum speed of the motorcyclist to prevent him from skidding? ($g$ = acceleration due to gravity)

$A$ car sometimes overturns while taking a turn. When it overturns,which wheel leaves the ground first?

$A$ car moving on a horizontal road may be thrown out of the road when taking a turn due to:
