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

$Mass,m=150kg$

$Speed,v=36kg/hr=10m{s}^{-1}$

$r=30m$

The horizontal force required to make the scooter to turn is the centripetal force.

$Force=\frac{m{v}^2}{r}$

$=150\times \frac{10\times 10}{30}=500N$
