Answer 1

Hey Mate! ❤❤❤

Let's solve! ✍

For an object rolling without slipping, linear translation velocity v and angular velocity of rotation ω are related as,

v=ω×R, where R is radius of the object.

v=36 km/hr=36 × (5/18)=10 m/s

ω=10×1=10 rad/s

1 revolution=2π rad/s

Answer:

ω = 10/2π revoltions per second.

Hope it helps! ☺✌
