1. The problem statement, all variables and given/known data A rope of negligible mass passes over a pulley of negligible mass attached to the ceiling. One end is held by student A (70 kg) who is at rest. The other side has student b (60 kg). I need to explain why or why not student b can lift student a off of the ground if he accelerates up the rope, increasing tension. 2. Relevant equations the force of student A is 700 N (70kg x 10 m/s^2) the force of student B is 600 N (60kg x 10m/s^2) the normal force exerted on student A by the floor is 100N (?) the force of tension will vary depending on student B's acceleration (F=ma) 3. The attempt at a solution I don't believe that it would be possible to pull the person holding the rope up, but i'm not sure how to prove it.
