Question

A circular track has a circumference of 34 cm with AB as one of its diameters.A cyclist travels from A to B along the circular path with a constant velocity of 15.7m/s. Find
(i) the displacement
(ii) the distance moved by the cyclist.

Answer 1

Ans i> the displacement = diameter of circular track
now, circumferance=$\pi d$
therefore,d=$\frac{34*7}{22}$
⇒d=10.80
therefore, the displacement =10.80 cm.
Ans ii> Sience the diameter divides the circle into to halves
therefore, the distance travelled by the cyclist=34/2= 17 cm.

HOPE THIS WILL HELP YOU.....!!!!!
