say u r in a elevator, and suddenly the cable that holds the elevator got disconnected and u r falling to the ground while standing,and dropping really fast from 15th floor. you would die right ? this is the question.. just before the elevator crashes on the surface what if you jump ? would...

hey guys I am stumped on this project: make a 2 floor elevator. i am going to use an H-bridge to control which way the motor spins (ie. clockwise will make the elevator go up, counter - down). anyway, here are the initial conditions to be met: elevator must stop at both floors elevator will...

I'm stuck on some lab questions I have to answer in my physics class. In the lab we held a spring scale in an elevator. We recorded his weight of the scale to be 9.5 Newtons. We rode the elevator up and down and recorded the maximum and minimum readings on the scale. The maximum reading up...

Anyone ever see those lists of funny things to do in an elevator? Well, let's make one. A friend and I came up with a bunch: Pretend to be alseep leaning against the button pannel. Offer everyone on the elevator sailor hats and name tags. ask them to call you Captain, and push the buttons...

"There is a lit candle in an elevator mounted on a bracket attached to the middle of one wall (say, 2" from the wall). A drop of mercury is on the floor. The cable snaps and the elevator falls. What happens to the candle and the mercury?" From...

I ran across this physics problem in class yesterday, it seems simple but...... (assume simplest case) ok...a screw at the top of an elevator that is traveling upwards comes loose and falls. Does the elevator speed going up effect the free fall time? (like does the elevator move toward the...

how can i find the answer w/o knowing the mass? A student stands on a bathroom scale in an elevator at rest on the 64th floor of a building. The scale reads 818 N. As the elevator moves up, the scale reading increases to 950 N, then decreases back to 818 N. Find the acceleration of the elevator.

A glass marble is dropped down an elevator shaft and hits a thick glass plate on top of an elevatior that is descending at a speed of 2.0 m/s. The marble hits the glass plate 3.0 m below the point from which it was dropped. If the collision is elastic how high will the marble rise, relative to...

Okay, we're learning relative motion in class and I just want to see if I am uderstanding things correctly. Okay there is a guy in an elevator and the elevator is on the ground. Also on the ground (outside of the elvator) is a ball. A ball is shot upward with Vo = 7 m/s. At the same time, the...

Hi, here is the question: there is a elevator, an man is in it, via a pulley he can raise the elevator. zzzzz/o\ zzzzz|zz\ zzzzz|zz| ---zz|------ |zzzz|zzzzz| |zzzz|zzzzz| |zzz\o/zzzz| |zzzz|zzzzz| |zzz/z\zzzz| ------------ This is my picture so can't do better z are empty...

if I drop a vibrating 440 Hz tuning fork down the elevator shaft of a tall building and when I hear a freq. of 400 Hz, is it possible to determine how far has the tuning fork fallen? My friend said yes but I think no. Am i right?
