Question 8 10 pts A person stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.72 of his/her regular weight. Calculate the acceleration of the elevator and find the direction of acceleration. (Choose upward as the positive direction and express the direction of the acceleration using the sign of the result, which must be in units of mis and include 2 digit after the decimal point. Maximum of 5%...

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...

As part of a physics experiment, you stand on a bathroom scale in an elevator. Though your normal weight is 630 N , the scale at the moment reads 710 N . Part A Is the acceleration of the elevator upward, downward, or zero? Part B Explain Part C Calculate the magnitude of the elevator's acceleration. Express your answer using two significant figures. Part D What, if anything, can you say about the velocity of the elevator? Explain.

A 500 N physics student stands on a bathroom scale in an 850-kg (including the student) elevator that is supported by a cable. As the elevator starts moving, the scale reads 400 N. (a) Find the acceleration of the elevator (magnitude and direction -- take up to be the positive direction). (b) What is the acceleration if the scale reads 620 N? c- If the scale reads zero, what is the acceleration of the elevator? Should the student worry? Explain...

A 596-N physics student stands on a bathroom scale in an 849-kg (including the student) elevator that is supported by a cable. As the elevator starts moving, the scale reads 449 N. a)Find the magnitude of the acceleration of the elevator. b) What is the acceleration if the scale reads 659 N ? c) If the scale reads zero, should the student worry? Explain. d)What is the tension in the cable in part A? e)What is the tension in the...
A 72 kg man stands on a bathroom scale in an elevator. Starting from rest at...
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...
