Block A hangs from a light string that passes over a light pulley and is attached to block B, which is on a level horizontal frictionless table, as shown above. Students are to determine the mass of block B from the motion of the two-block system after it is released from rest. They plan to measure the time block A takes to reach the floor. The students must also take which of the following measurements to determine the mass of block B?   a. Only the mass of block A b. Only the distance block A falls to reach the floor c. Only the mass of block A and the distance block A falls to reach the floor d. The mass of block A, the distance block A falls to reach the floor, and the radius of the pulley
