Chapter 4 Problem 42
A woman stands on a scale in a moving elevator. Her mass is 63.0 kg, and the combined mass of the elevator and scale is an additional 790 kg. Starting from rest, the elevator accelerates upward. During the acceleration, the hoisting cable applies a force of 9130 N. What does the scale read (in N) during the acceleration?
First find acceleration of elevator
Net force =mass *acceleration
where M =mass of person +mass of elevator and scale =63kg+790kg=853kg
==========
Support force on the scale ,
========
Now the scale will be calibrated for g (9.81m/s2 )

An elevator cabin has a mass of 358.1 kg, and the combined mass of the people inside the cabin is unknown. The cabin is pulled upward by a cable, when the elevator is at rest, the tension in the cable is 5167.54 N, what is the combined mass of the people inside cabin? When the elevator accelerates downward, the tension in the cable is 4000 N, What is the acceleration of the elevator?
A 535.4-N physics student stands on a bathroom scale in an elevator that is supported by a cable. The combined mass of student plus elevator is 761.2 kg Part A What is the acceleration if the scale reads 416 N as the elevator starts moving? Notice that g 9.8 m/s2 and the sign of the acceleration is determined by the direction. For example, the gravitational acceleration is -g--9.8m/s as the gravitational force points downward m's Submit Request Answer Part B...
a person stands on a scale inside an elevator at rest. The scale read 800 N. a) The elevator accelerates upward momentarily at the rate of 2 m/s2 . What does the scale read then? I am confused here. please give me a hand preferably with a free body diagram. I am bad at physics
A woman stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.77 of her regular weight. Calculate the magnitude of the acceleration of the elevator.
Henry, whose mass is 95 kg, stands on a bathroom scale in an elevator. The scale reads 830 N for the first 2.8 s after the elevator starts moving, then 930 N for the next 2.8 s. What is the elevator's speed 5.6 s after starting?
A 72 kg man stands on a bathroom scale in an elevator. Starting from rest at the top floor, the elevator descends, attaining its maximum speed of 1.20 m/s in 0.80 s. It travels with this constant speed for the next 5.00 s. The elevator then slows down for 1.50 s and comes to rest at ground level. a)What is the acceleration of the man during the first 0.80 s? Answer in units of m/s2 and use the upward direction...
