A block and a spool have the same mass, and are each pulled across a level, frictionless surface by a string, as shown to the right. The string pulling the spool is wrapped around it many times, and the other string is fastened to the center of the block. Both hands pull with the same force, starting at the same instant, and maintain a constant tension.
A) Describe how each object moves on the frictionless surface in terms of both translation and rotation.
B) Does the hand pulling the spool’s string move faster, slower, or at the same speed as the other hand in order to maintain the same tension in the strings? Explain.
C) Which object, if either, passes the finish line first? Explain your reasoning.
