A cable is lifting a construction worker and a crate, as the drawing shows. The weights of the worker and crate are 961 and 1540 N, respectively. The acceleration of the cable is 0.620 m/s2, upward.
(a) What is the tension in the cable below the worker?
(b) What is the tension in the cable above the worker?
b) I don't have the drawing. But tension above the worker has to support massbelow*g, and provide mass*a to accelerate.
