A 75.6 kg person stands on a scale in an elevator. What does the scale read (it reads massunits, not weight units) when the elevator is accelerating downward at 3.00 m/s^2?"

Solution Summary

With a diagram and complete formulas, the problem is solved.

A 75.0 kg person stands on a scale in an elevator. What is the apparent weight in each of the following situations?
(a) when the elevator is accelerating upward with an acceleration of 1.80 m/s2
(b) when the elevator is moving upward at a constant speed
(c) when the elevator is acceleratingdownward with an acceleratio

You step into an elevator at the 10th floor and press the 2nd-floor button. The elevator accelerates downward briefly as it picks up speed. There are two forces acting on you: the floor pushing up on you and gravity pulling down. Compare these two forces while the elevator is acceleratingdownward. explain your answer in terms

The weight of a book was measured using a scale. The scale showed 15N. Next, the book and the scale were placed in an elevator that does not show the floor number. When the elevator started moving, the reading of the scale has changed, but later was reading 15N again. Using the fact that the scale shows the same value in the ele

A 6.00 kg box is sliding across the horizontal floor of an elevator. The coefficient of kinetic friction between the box and the floor is .360. What is the kinetic frictional force that acts on the box when the elevator is a.)stationary, b.) accelerating upward with an acceleration whose magnitude is 1.20 m/s^2 and c.) accelera

For the following questions, the answers are given but I need the workings to arrive at the answer.
1. A force acts on a 1.5 kg, mass, giving it an acceleration of 3.0 m/s^2. (a) If the same force acts on a 2.5 kg mass, what acceleration would be produced? (b) What is the magnitude of force?
Answer: (a) 1.8m/s^2 (b) 4.5 N

A 3.8KG BOX IS SLIDING ACROSS THE HORIZONTAL FLOOR OF AN ELEVATOR. THE COEFFICIENT OF KINETIC FRICTION BETWEEN THE BOX AND THE FLOOR IS 0.470. DETERMINE THE KINETIC FRICTIONAL FORCE THAT ACTS ON THE BOX FOR EACH CASE.
THE ELEVATOR IS STATIONARY
THE ELEVATOR ACCELERATES UPWARDS AT 2.0 M/S2
THE ELEVATOR ACCELERATES DOWNWARD A

A workman carries a sheet of metal up to the roof of a skyscraper by transporting it in the building's elevator. Inside the elevator, the metal sits at an angle of 26o from the horizontal. The workman absentmindedly places his toolbox on the smooth metal surface, and it begins to slide with negligible friction.
a. Draw a free

A person stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.790 of the person's regular weight.
1) Calculate the acceleration of the elevator
2) Find the direction of the acceleration
Positive y-axis points UP.
