Question

A park has a radius of 10 m. If a vehicle goes round it at an average speed of 18 km/hr, what should be the proper angle of banking ?

Answer 1

Radius of park r = 10 m

Speed of vehicle = 18 km/hr = 5 m/sec

Angle of banking is given by,

$tan\theta =\frac{v^2}{rg}\Rightarrow \theta =ta{n}^{-1}\frac{25}{rg}=ta{n}^{-1}\frac{25}{100}=ta{n}^{-1}\left(\frac{1}{4}\right)$
