answered-by-expert Expert Answer
Speed v of tip of minute hand, v = ω × r
 
where ω is angular speed of rotation and r is length of minute hand.
 
If T = 60 minute is time period of one rotation of minute hand , then
 
begin mathsize 14px style omega space equals space fraction numerator 2 straight pi over denominator 60 cross times 60 end fraction space equals space 1.745 space cross times space 10 to the power of negative 3 end exponent space r a d divided by s end style
Speed of tip v = 1.745 × 10-3 × 0.1 m/s = 1.745 × 10-4 m/s

At t=0 a bead of mass m is placed at a distance \frac{L}{2} from the axis of rotation. Initial speed of the bead is zero with respect to the rod. The rod is rotated with a constant angular velocity o as shown in diagram. Find the velocity of bead w.r.t ground, when it leaves out of the rod. (Given L is the length of rod.)
