A pulley has a negligible mass (that means, the radius is not relevant).  It is supported with a pin at the center (and is free to rotate).  A rope goes over the pulley.  Block A, which has a mass of 5.723 kg is connected to one side of the rope.  On the other side, Block B, with a mass of 12.602 kg is connected.   The system is released from rest. What is the speed of block B, after B has traveled 0.716 m?  Please enter a positive value in m/s (but without units) regardless of the direction of the motion of B

A pulley has a negligible mass (that means, the radius is not relevant).  It is supported with a pin at the center (and is free to rotate).  A rope goes over the pulley.  Block A, which has a mass of 5.723 kg is connected to one side of the rope.  On the other side, Block B, with a mass of 12.602 kg is connected.

 

The system is released from rest.

What is the speed of block B, after B has traveled 0.716 m?  Please enter a positive value in m/s (but without units) regardless of the direction of the motion of B
