Question

Derive an expression for maximum safe the speed of circular motion of a car on level road?​

Answer 1

Explanation:

$\begin{gathered}\huge\star{\pink{\underline{\mathfrak{answer}}}}⋆ \\\end{gathered}$

N = mg

Static friction provides centripetal acceleration

fs =< μsN

mv2/r =< μsN

v2 =< μsNR/m = μsmgR/m = μsRg

v =< √ μsRg

This is the maximum speed of a car in circular motion on a level road.
