Question
A car is moving with constant speed on a rough banked road.
Figure (i), (ii) and (iii) show the free body diagram of car A, B & C respectively:-
Options
A.Car A has more speed than car C
B.Car A has less speed than car B
C.FBD for car A is not possible
D.If µ > tanθ the FBD for car C is not possible
Solution
Sol. If speed is less tendency of sliding is downward and friction up the plane for high speeds friction is down the plane.
