Vector displacement

  1. Sep 26, 2011 #1
    1. The problem statement, all variables and given/known data
    The minute hand on a watch is 2.0cm in length. What is the displacement vector of the tip of the minute hand:
    a. from 8:00 to 8:20
    b. From 8:00 to 9:00

    2. Relevant equations

    3. The attempt at a solution
    I keep getting that the displacement is 1.8,2.8, but the program we have to put it in for class it keeps frickin saying "Almost... blah blah blah some crap about checkin sig figs.

    How are you arriving at these results?

    A displacement vector consists of a magnitude and direction.

    In other words, after 20 minutes, how far did the tip of the minute hand move and in what direction?
