Answer #1

A) The tension in the rope is T- mg (89 kg)(9.80 m/)-8722N B) The tension in the rope if the box has vy- 8.0 m s andis speeding up at 80 m/s2 is T-m(atg)-(89 kg)(9.80 m/s+8.00 m/s)-1584 N

    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. Draw a FBD for each mass Find the tension in each rope...
