A heavy man’s resting weight is 1029 N. He is standing on a scale on an elevator that has a mass (without the man) of 1250 kg. While the elevator is in motion the man’s apparent weight reads 1134 N. The tension on the cable supporting the elevator is (in N)? The answer is 14,634 N but I do not know how to get the answer. Please provide a detailed explanation.

Suppose Arturo is standing on a spring bathroom scale in an elevator, which is at rest, on the 15th floor. What is his acceleration? What forces are acting on him? What is the reading (in Newtons) on the bathroom scale if he has a mass of 150 kg? (Draw it out and Label it) Now imagine disaster - the rope holding the elevator snaps, there are no safety features, and the elevator plunges down the shaft in free fall. Herrera...

all of question 2
2 Indoor Climbing (10) Joff climbs up a wall at an indoor climbing gym using an auto belay-device. The auto-belny device exerts an upward force equivalent to the weight of 10kg of mass, in order to quickly take up slack while climbing. Joff weighs 700 N and climbs upward with a constant speed of 0.50 m/s. a) What is his acceleration? b) What force pushes Joll up the wall while he climbs? Why? c) Sketch a...
