Homework Statement
A cable is lifting a construction worker and a crate, as the drawing shows. The weights of the worker and crate are 921 N and 1330 N, respectively. The acceleration of the cable is 0.620 m/s2, upward. What is the tension in the cable (a) below the worker and (b) above the worker?
Homework Equations
F=ma.
The Attempt at a Solution
The tension below the worker is (921+1330)*.62=1395.62 N ; I came across this answer by mistake but found it to be correct. However, how does one find the tension in the rope above the worker? Why wouldn't it be identical to the tension below him, since both weights are being pulled downward by gravity?
