An Atwood pulley is shown above. Rather than masses, two students hold on to either end of the rope of negligible mass. One end of the rope is held by Student A of mass 100 kg, who is at rest on the floor. The opposite end of the rope is held by Student B of mass 80 kg, who is suspended at rest above the floor. (a) On the dots below that represent the students, draw and label free-body diagrams showing the forces on Student A and on Student B. A B (b) Calculate the magnitude of the force exerted by the floor on Student A. Student B now climbs up the rope at a constant acceleration of 0.35 m/s with respect to the floor. (c) Calculate the tension in the rope while Student B is accelerating. (d) As Student B is accelerating, is Student A pulled upward off the floor? Justify your answer. (e) With what minimum acceleration must Student B climb up the rope to lift Student A upward off the floor? Student A 100 kg Student B 80 kg
