Newton's Laws of Motion

  1. Jul 14, 2012 #1
    At the instant that one-fourth of block 1 remains on block 2, x2+l=x1+(l/16).

    For days trying to figure out how this equation derived from.
    Thank You.

    hi azizlwl! :smile:

    (i don't understand why they've put lengths on both sides of the equation, but …)

    x1 and x2 are the distances blocks 1 and 2 have moved

    since block 1 has to overtake block 2 by (15/16)l, that means x1 - x2 = (15/16)l :wink:
