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 80 kg, who is at rest on the floor. The opposite end ofthe rope is held by Student B of mass 70 kg, who is suspended at rest above the floor.
(I will provide the image referenced to below)
Student b now climbs up the rope at a constant acceleration of .5 meters per second squared with respect to the floor.
a. Calculate the tension in the rope while Student B is accelerating.
b. As student B is accelerating, is student A pulled upward off the floor? Justify your answer.
c. With what minimum acceleration must student B climb up the rope to life student A upward off the floor?
The Attempt at a Solution
I solved in other problems related to this that the normal force exerted by the floor on student A is 100 N, and I tried to do part A (I will post pictures in a minute). Part B and C I am very unsure of, and I do not know where exactly to begin with these parts. If I could have any/all hints at a direction for part B and C, that would be greatly appreciated 8D.
Pictures coming in a reply.
