Homework Help: Weird problem

  1. Mar 27, 2005 #1
    hi there, first post, hopefully not many more to come, i can usually do these problems but im swamped, but then so is everyone else, just cant think about this stuff....

    You are in an elevator at the top of the CN tower. You have a pendulum and allow it to oscillate. The elevator falls to the ground after someone cuts its support cables. What does the pendulum do? Ignore the air resistance acting on the pendulum and the elevator. (the CN tower is the worlds tallest free-standing structure (not for long) in Toronto, Canada)

    the only thing i can come up with is that since the elevator is moving down at a great speed, does the pendulum move slower relative to a pendulum on the earth?

    thanks for any help you can provide

    Think about the force of gravity inside the elevator. Is it the same as something that isnt in free fall?

    It is a weird problem because theres a lot of things the pendulum can do, depending on the string / cable.
