Hi,
I'm not sure if this mechanics question should be in the Maths forum or the physics forum Nevertheless, I apologise first if I have posted in the wrong area
I was wondering if anyone could help me with the following question.
A lamina moves in its own O(x,y) plane. At a certain instant the displacement from one of its points P to another point Q is (-5i+10j). If the velocity of P is (7i-2j) and the velocity of Q has 5 as its x component:
1) What is the angular velocity of the lamina?
2) What is the velocity of Q?
In my notes I have been given the following equation:
[tex]v_Q[/tex] = [tex]v_P[/tex] + [tex]\\omega\\[/tex] + [tex]\\vec{PQ} [/tex]
I've got the information for velocity of P and the displacement but I'm not sure how to express the velocity of Q in vector format? And how to I find the angular velocity? Is it just rearranging the equation for omega?
Please help, thanks!
