Derive an expression for the maximum velocity of a car during circular motion on a level road. |
| Answer» N = mg\xa0Static friction provides the centripetal acceleration\xa0fs =< μsN\xa0mv2/r =< μsN\xa0v2 =< μsNR/m = μsmgR/m = μsRg\xa0v =< √ μsRg\xa0This is the maximum speed of a car in circular motion on a level road | |
