Question

a particle moves along a circle of radius R=1 m so that its circumference rotates with constant angular velocity 2 rad/s. the linear speed of the particle is  ?

anonymous · Answer

$$v=r\omega$$$$v=1\times2$$$$v=2ms^{-1}$$

anonymous · Answer

no thats absolutely wrong

angular velocity about centre= 2(angular velocity about any point on its circumference)

ω=2 (2) rad/s

v = rω = 1(4) m/s

anonymous · Answer

Angular velocity is the same at any radius, that's the point of it :)

anonymous · Answer

no u cannot consider it like that

anonymous · Answer

Why not?

anonymous · Answer

angular velocity about centre is different from angular velocity about a point on circumference because the coordinates are going to change

anonymous · Answer

I may have the wrong scenario here.|dw:1316678995512:dw|What I'm getting from the question is that the centre of the circle is stationary, and the circumference is rotating about the centre at an angular velocity of 2 rad/s due to a particle attached to it. You have to find the linear velocity of that particle. Is this the case?
