A rope of negligible mass passes over a pulley of negligible mass attached to the ceiling, as shown above. One end of the rope is held by Student A of mass 70 kg, who is at rest on the floor. The opposite end of the rope is held by Student Bof mass 60 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.

Question attached for pulley- force and acceleration

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 0.25 m/s with respect to the floor. c. Calculate the tension in the rope while Student Bis accelerating. d. As Student Bis 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?
