Homework Help: What is the acceleration of a book on a bookshelf

  1. May 3, 2008 #1
    1. The problem statement, all variables and given/known data
    If a book falls off a bookshelf
    What is its acceleration?
    How fast will it have fallen after 1 second?
    I wonder if someone could tell me how to work this out.
    Does it depend on the size of the book, and do I need any other information.
    This is all the problem says.

    Many thanks

    Didn't you even try to solve it?

    if a book falls off a bookshelf, wouldn't it's acceleration be 9.8 m/s2?

    u=0, t=1, a=9.8 m/s2
