Three belts move over two pulleys without slipping in the speed reduction system. Point A on the input belt moves to the right with a constant spped of 0.6m/s. Determin the velocity of point C on the output belt, and the acceleration of point B on the output pulley.

2. Relevant equations

Va = Vo + wr

where Vo is the velocity of center of left pulley which is equals to 0m/s

so Va = wr

3. The attempt at a solution

with the above equation I found out that the angular velocity of the pulley is

0.6m/s = (0.1)w

w = 6rad/s clockwise direction

and this means that the pulley is rotating with the speed of 6 x radious of bigger part of pulley = 0.6m/s and from the picture we can deduce that the pulley on the left also rotating with same speed.

This is my assumption and i dont think this is right, and even though this is right how can i find the Vc and acceleration at point B?
