Question

A scooter weighing 150 kg together with its rider moving at 36 km/hr is to take a turn of radius 30 m. What horizontal force on the scooter is needed to make the turn possible ?

Answer 1

Given that,

$m=150kg,v=36km/hr=10m/sec,r=30m$

Horizontal force needed

$=\frac{m{v}^2}{r}=\frac{150\times (10{)}^2}{30}=\frac{150\times 100}{30}=500N$
