Question

a cyclist goes around a circular track once every 2minute ifthe radius of the circular track is 110m calculate the speed of the cyclist

Answer 1

Speed = (2*π*110) ÷ (2*60)
= 5.76 m/s

Answer 2

■HEY DEAR

Answer:- 5.76 m/s

Explanation:- we know that for a body moving in a circular path:

v= 2pie r / t

here. speed , v= ? (to be calculated)

•°•Radius of circular track , r= 110

And, Time taken for 1 round, t =2 minutes

= 2×60sec

=120sec.

Now,

putting these values of (pie) , (r ), and (t) in the above formula , we get:-

v= 2×22×110

7×120

=5.76m/s

Thus, the speed of cyclists on the circular track is 5.76 metres per second.
