Time intervals measured with a stopwatch typically have an uncertainty of about 0.2 s, due to human reaction time at the start and stop moments. What is the percent uncertainty of a handtimed measurement of (a) 5 s, (b) 50 s, (c) 5 min?

    Hint: This seems like a trick question ;)

    Percent uncertainty is usually just the uncertainty times by 100!

  • Physics -

    a) 4%
    b) 0.4%
    c) 0.07%
