A wooden crate with mass m = 44 kg sits on the ground. Judy attaches a rope to the crate, and leads the rope ver- tically over a frictionless pulley that is fixed to the ceiling. While standing on a chair, Judy grabs the free end of the rope that has been run over the pulley. Then she steps off the chair. If she sinks back to the ground with an acceler- ation of a = 1.9 m/s2, then what is Judy's mass M?

Judy attaches a rope to the crate, and leads the rope ver-
tically over a frictionless pulley that is fixed to the ceiling.
While standing on a chair, Judy grabs the free end of the
rope that has been run over the pulley. Then she steps off
the chair. If she sinks back to the ground with an acceler-
ation of a = 1.9 m/s², then what is Judy's mass M?
Expert Solution
Introduction:
We are given mass of crate. We are also given the acceleration of the system. We have to find the mass of Judy. We apply 2nd law of motion for both bodies and obtain 2 equations. We solve them to find mass of Judy.
