Question

A cyclist riding a bicycle at a
constant speed of 10 m/s on a
circular track. The cyclist completes
the three rounds of a track in 6
minutes. What is the radius of the
circular track?​

Answer 1

Explanation:

It is given that,

v=72Km/hr

=

18

5

×72=20m/s

radiusr=80m

Bending of a cyclist in circular motion is given by the relation as

tanθ=

rg

v

tanθ=

80×10
