Circular motion of a car on a banked road
mg= Weight of vehicle
N= Normal reaction exerted on vehicle
f = Frictional force
`theta` = Angle of banking
`a=(v^(2))/(R)` = Centripetal acceleration.
`fcostheta` = Horizontal component of frictional force
`fsintheta`= Vertical component of frictional force
`Ncostheta` Vertical component of normal reaction.
`Nsintheta` = Horizontal component of normal reaction.
