You hop on at the second floor and step onto the scale before pressing the button to travel down to the first floor. Before the doors close, while the elevator isn’t moving, you have a weight of 934 ?. As soon as the elevator starts downward, the scale reads 813 ?. What is the magnitude of the acceleration of the elevator?
for the question i need to do the following
1- Draw a free body diagram
2. set up a coordinate system. You must correctly follow our rule to align the net acceleration for the
system to be along a single axis (it cannot have an x- and a y-component).
3. Correctly set up Newton’s Second Law (sum of the forces) in both the x- and y- direction. Correctly use
either sinθ or cosθ as appropriate.
question ----- Your physics professor told you that you feel heavier or lighter in an elevator at the beginning or end of
your vertical voyage. You want to test if your weight ACTUALLY changes, so you take a bathroom scale
with you to the rickety elevator in Elings hall. You hop on at the second floor and step onto the scale
before pressing the button to travel down to the first floor. Before the doors close, while the elevator
isn’t moving, you have a weight of 934 ?. As soon as the elevator starts downward, the scale reads
813 ?. What is the magnitude of the acceleration of the elevator?
weight, W = mg = 934 N
reading, R = 813 N
