# What is the acceleration of a book on a bookshelf

## Homework Statement

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

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

HUGE SPOILER

$$v(t)=a(t)t+v_{0}(t)$$
