... The tension in the third rope is 94.3 N directed 58.0 below the horizontal. 5.14. Model: We assume that the passenger is a particle acted on by only two vertical forces: the downward pull of gravity and the upward force of the elevator floor. Visualize: Please refer to Figure Ex5.14. The graph has ...
