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 :

Velocity of the scooter, v = 36 km/hr

= 36 × 5/18 m/s


= 10 m/s


Mass of the scooter, M = 150 kg


The turn will be possible when the both the forces acting on the scooter, radially inward and outwards the turn balance out.


Horizontal force required = centripetal force


=Mv2/Radius


=150×10×10/30


=500 N
