Calculating Distance and Speed of a Falling Hammer

[kelsobrooks]

Homework Statement

OK... Hammer falls from building and after 1 second has fallen 1 story...
How FAR has it fallen after 2 seconds?

Homework Equations

d= s x t

The Attempt at a Solution

So, doesn't that mean the Average Speed for 1 sec is 1 story/sec?
How do I calculate the "Instant" speed at the 1 second mark?

Also I am wondering
how to fiqure the Accelereation in "Stories per Second"

I keep coming up with the acceleration is 1 Story per second/second.

I keep getting confused.

Thanks

The hammer is under the influence of gravity only.

x=ut+0.5at²

Use the initial information to get the initual velcoity 'u'.
