28. A cyclist speeding at 18 km/hr on a level road takes a sharp turn without reducing the
speed. (Radius of the circular path = 3m)
(a) Centripetal force is provided by
(b) Derive an expression for safe speed of the cyclist at the turning.
2.
(C) If the coefficient of friction between the tyre and the road is 0.10, will the cyclist
slip while taking the turn ?

How r u??

Here's ur answer

(C)

Moment of inertia for disc = MR²/2

Moment of inertia for ring = MR²

Hence, ring will have more moment of inertia

28)

Neccessary centripetal force is provided by frictional force

Parts of the question is not clear for me yaar

I could understnad only thes 2 questions

Sorry dude +_+
