2003B1 (15 points) 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 B
of 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.
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/s2 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?
