When a person throws a meter stick it is found that the centre of the stick is moving with speed `10 m//s` and left end stick with speed `20 m//s`. Both points move vertically upwards at that moment. Then angular speed the stick is :

A

`20 rad//sec`

B

`10 rad//sec`

C

`30 rad//sec`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Angular velocity, `omega = (20 - 10)/(0.5) = 20 rad//sec`.

Calculate the angular speed of againt wheel of radius 10 m, moving with a speed of 10m//s .

A metre stick is pivoted about its centre. A piece of wax of mass 20 g travelling horizontally and perpendicular to it at 5 m/s strikes and adheres to one end of the stick so that the stick starts to rotate in a horizontal circle. Given the moment of inertia of the stick and wax about the pivot is 0.02 kg m^(2) , the initial angular velocity of the stick is :
