A cyclist is riding with a speed of 18 kmh-¹. As he approaches a circular turn on the road of radius 25√2 m, he applies brakes and reduces his speed at the constant rate of 0.5 ms-¹ every second. Determine the magnitude and direction
of the net acceleration of the cyclist on the circular turn.
Answers & Comments
Speed of the cyclist ,
v= 18km/hr
As the cyclist approaches the turn..
The tangential acceleration
And the radial acceleration:-
Thus..
Total acceleration
And the Direction..
hence,
magnitude of net acceleration of the cyclist is
and direction of net acceleration of cyclist is
