Solve the following problem given below:
Problem: A block of mass m sits on a horizontal frictionless tabletop. It is connected by a light rope that passes over a light frictionless pully to a block of mass 5 kg that is suspended from the end of the rope. The blocks are released from rest and the 5 kg block descends downward 6 meters in 3 seconds.
Part I: While the blocks are moving, what is the tension in the rope?
Part II: What is the mass m of the block on the table?
