Q18 of 23 Page 117

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

According to the question;

Radius of circular path (r) = 30 m;


Velocity of scooter (v) = 36 km/hr;


= m/s;


= 10 m/s.


Mass of scooter (m) = 150 kg;


For making the turn possible the scooter needs force equal to the centripetal force which is given by;


F =


⇒ F =


⇒ F = 5 x 10 x 10 = 500 N.


The force required is 500 N and it is provided by the normal reaction between the ground and the scooter.
