    Falling
In summary, the person is trying to calculate the distance the hammer has fallen after 2 seconds, given that it fell 1 story in 1 second. They are also wondering how to calculate the "instant" speed at the 1 second mark and the acceleration in "stories per second." They are using the equation d= s x t and x=ut+0.5at2, and need to find the initial velocity 'u'.

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'.
 

1. What is the purpose of a "Hammer Free Falling 1 story" experiment?

The purpose of a "Hammer Free Falling 1 story" experiment is to study the effects of gravity on a falling object. It is a common experiment used to demonstrate the concept of acceleration due to gravity.

2. How does the height of the drop affect the results of the "Hammer Free Falling 1 story" experiment?

The height of the drop does not affect the results of the "Hammer Free Falling 1 story" experiment. The acceleration due to gravity remains constant regardless of the height of the drop. However, a higher drop allows for a longer time to measure the effects of gravity and can produce more accurate results.

3. What materials are needed to conduct a "Hammer Free Falling 1 story" experiment?

The materials needed for a "Hammer Free Falling 1 story" experiment include a hammer, a measuring tape, a stopwatch, and a flat surface to drop the hammer on. Optional materials may include a video camera for recording the experiment and a calculator for data analysis.

4. How does air resistance affect the results of the "Hammer Free Falling 1 story" experiment?

Air resistance can affect the results of the "Hammer Free Falling 1 story" experiment if it is not controlled. To minimize the effects of air resistance, the experiment should be conducted in a vacuum or in an area with minimal air resistance. This will ensure that the hammer is falling at a constant rate and the results are not affected by external factors.

5. What are the safety considerations when conducting a "Hammer Free Falling 1 story" experiment?

Safety should always be a top priority when conducting any experiment. For the "Hammer Free Falling 1 story" experiment, it is important to ensure that the area is clear of any obstacles or people, and that the hammer is dropped straight down without any sideways motion. Eye protection should also be worn in case the hammer bounces back upon impact. Additionally, the experiment should be conducted on a stable surface to prevent any accidents.
