Question

A stone tied to a strong is made tn resolue in a horizontal circle of radius 4m with angular speed of 2 radian,persecond with what tingential velocity will the stone move off the circle if the string cuts

Answer 1

The tangential velocity will be the same as the value just before the string is cut:
(Radius)*(Angular Velocity) = 4 * 2 = 8 m/s

Answer 2

Tangential velocity=radius of circle -:- angular speed=4-:-2=2m/s

Answer 3
