Homework Help: Average Speed vs. Instantaneous Speed

  1. Feb 6, 2014 #1
    1. The problem statement, all variables and given/known data
    A book falls off a shelf and lands on the floor. Which is greater, the book's average speed or its instantaneous speed right before it lands?

    2. Relevant equations
    v = d/t

    3. The attempt at a solution
    I think its the instantaneous speed because the book accelerates over time.
