Class 11 Physics Laws of Motion Motion of a car on a level road

Motion of a car on a level road

 

 N = mg

Static friction provides the centripetal acceleration

fs =< μs

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
