Question

Establish the relation: V= wr V= linear speed ,wr = angular speed, r = radius of the circular path.

Answer 1

You're moving in a circle of radius r, so the distance you travel in one full trip round the circle is 2.pi.r and you're doing it in one time period, T

speed, v = distance/time = 2.pi.r/T

w = angular speed, and you complete 2 pi radians in time T, so w = 2pi/T

so v=rw
