Question

A motor cyclist goes round a circular race course of
radius 160 m at 144 km h-1. How far from the
vertical must he lean inwards to keep his balance ?
Take g = 10 ms?
​

Answer 1

Answer:

Angle to which he should bend is

tanθ =v2rgv=144km/hr =40m/sd=320m , r= 160mtanθ =v2rg=40×40160×10tanθ =1or θ = 450
