Does the water spill?

  1. Dec 31, 2014 #1
    Is it possible to predict whether or not water spills out of a cubical container accelerating uniformly along a specific incline?
    I know the expression for the angle the new water level makes with the old one(horizontal).
    But how do I know their point of intersection?
    Note : Of course the container is not full.

    Could you be a little more vague? I can almost understand what you are asking but if you could just obfuscate the issue a bit more, I could be completely baffled :smile:

    Ok. The actual question itself then.
    An open cubical container with 2.5 m x 1 m base and 2 m height, half full with water is accelerated at 4ms-2 up on a 15 degree incline along its length. Will the water spill?

    Indeterminate since you have not specified whether the long axis or short axis is pointing uphill. Don't you think that might matter?

    Oh, and by the way, you won't get any help here unless you show some work of your own. I'm just trying to get you to post a question that HAS an answer.

    EDIT: DOH !! You DID say "along it's length". I can't read.
