A car moves in a horizontal circle on a level road. The centripetal force is provided by:

A 2 kg body moves in a horizontal circle of radius 1 m with speed 3 m/s. The centripetal force in newtons is:

On a banked road with angle $\theta$, the ideal (frictionless) speed for safely negotiating a turn of radius $r$ is:

Limiting friction between two surfaces primarily depends on:

A body is sliding down a rough inclined plane making 30° with the horizontal at constant velocity. The coefficient of kinetic friction is:

A block of mass 5 kg rests on a horizontal surface. The coefficient of static friction is 0.4. What is the maximum static friction force?…
