Question

ws of Motion
The figure shows mass m moves with velocity u. Find the velocity of ring at that moment. Ring
is restricted to move on smooth rod.
Re= 60°​

Answer 1

Given:

The figure shows mass m moves with velocity u.  

To find:

Find the velocity of ring at that moment. Ring is restricted to move on the smooth rod. Re= 60°​

Solution:

From given, we have,

The figure shows mass m moves with velocity u.  

The ring is restricted to move on the smooth rod.

Re= 60°​

Consider the attached figure while going through the following steps.

u = v cos 60  

u = v * 1/2

2u = v

Therefore, the velocity of the ring at that moment when the ring is restricted to move on smooth rod Re= 60°​ is 2u
