    i guess it would be more likely to topple but surely that would start it sliding sooner?
    anyway imagine it doesn't

    I have two identical uniform plastic blocks, 2x1x1, on a slope of uniform roughness. One is standing up on end. As i increase the slope, which starts to slide first?? Can anyone reconcile this with friction=coefficient of friction*normal reaction force??

    (none of my physics or maths teachers could answer this, and i need it for a real life application)

    I agree with above but if n is a power of 2 you can do it without wasting any time, otherwise i think you have to waste time somewhere

    sorry for being so picky but i don't think you can use a exercise ball to crush a ping pong ball without picking it up
