Question 660: Centre of Mass and Rotational Motion

Question

A car of mass m is moving on a level circular track of radius R. If $$\mu $$
s
represents the static friction between the road and tyres of the car, the maximum speed of the car in circular motion is given by

Accepted Answer

For smooth driving maximum speed of car
v then
$${{m{v^2}} \over R} = {\mu _s}mg$$
$$v = \sqrt {{\mu _s}Rg} $$

Answer

$$\sqrt {{\mu _s}mRg} $$

Answer

$$\sqrt {{{Rg} \over {{\mu _s}}}} $$

Answer

$$\sqrt {{{mRg} \over {{\mu _s}}}} $$

Answer

$$\sqrt {{\mu _s}Rg} $$
