A mass m1=5.0 kg hangs suspended by a rope from an elevator ceiling. A second mass m2=5.0 kg hangs suspended by a rope from the bottom of mass m1. Starting from rest, the elevator ascends, attaining its maximum speed of 1.8 m/s in 0.80 s. The elevator travels with this constant speed for 5.0 s, undergoes a uniform negative acceleration for 1.5 s, and then comes to rest.

  1. Draw a FBD for each mass
  2. Find the tension in each rope before the elevator starts to move.
  3. Find the tension in each rope during the first 1.8 s of the elevator’s ascent
  4. Find the tension in each rope while the elevator is traveling at constant speed
  5. while the elevator is slowing down
