Homework Statement
Dynamic homework need help
Relevant Equations
Velocity, Angular velocity, acceleration , angular acceleration
Hi everyone,

I need help for this homework. I'm a mechatronics engineering student and i want to solve this question but no matter how hard I try, I can't solve the question. Sorry for my bad english...

The disk connected to the AB stick with a length of 2 meters is rolled as shown in the figure without slipping. The velocity and acceleration of point A at the given moment moves to the left with VA = 6 m / s and aA = 3 m / s ^ 2, as shown in the figure, respectively.

A-)Find the velocity of point B and the angular velocity of point AB.

B-)Find the acceleration of point B and the angular acceleration of the AB bar.

C-)Find the angular velocity and angular acceleration of the disc.

Thanks.

Welcome to the PF.

What "relevant equations" do you think may apply? Can you show us a couple of your failed attempts to work on this problem? Can you show us your free body diagram (FBD)? Thanks.

... and please post the diagram provided with the question. If you cannot do that, describe it thoroughly.

That's weird. The OP originally did have a diagram included. It was confusing, but it was there.

@Serhatakguc0 -- Did you delete the figure for a reason?

Until @Serhatakguc0 gets back, I did manage to scribble something down of the diagram he had:
