Two bodies with same speed?

Hello,

I've attached a a body on to another body via the Line joint. However, when I set the linear velocity for the attached body same as the main body, they do not move at the same speed.

In-depth explanation:

There are actually three bodies involved. The main body is actually a dummy static body so that the attached body does not affect the actual body. However, since static bodies can't be affected by force, I set its position to the actual body and set the velocity of the attached body to that of the actual body. The attached body moves slower but I want it to move the same speed as the actual body..

 

The dampening and the frequency are both 0 for the Line joint. The mass, and other settings are the same for all bodies involved.

 

What am I doing wrong?

 

(Btw, the reason I'm doing three bodies is because of this: http://farseerphysics.codeplex.com/discussions/262878 but this is for a different effect)
