Compute the speed per hour of a vehicle going `15 m` / `s`

Banking of road helps to increase the centripetal force and thereby increases the limit of maximum speed of vehicle with it can take the curve. Give the expression for the maximum allowed speed of a vehicle on a banked road with friction.

With the help of a free body diagram represent various forces acting on a vehicle moving on a banked road. Neglecting frictional force obtain the expression for the maximum safe speed of the vehicle on the banked road.

Banking of road helps to increase the centripetal force and thereby increases the limit of maximum speed of vehicle with it can take the curve. Sketch the schematic diagram of a vehicle on a banked road and mark the various force acting on it.
