## What is the resultant acceleration on the astronauts?

The first stage of the Saturn V rocket achieved a thrust of 3.3 x 10 power of 7N. It had a mass of 2.5 x10 power of 6kg.
a) What is the resultant acceleration on the astronauts?
b)Is this medically safe?
c)This stage fired for 168 seconds, how high was the rocket?

A) F = ma. You have F and m. Solve for a.
B) They weren’t killed or injured, so apparently the answer is “yes”. But you’re probably supposed to convert the answer in a to g’s by dividing by 9.8 m/sec^2. For instance 20 m/sec^2 is 20/9.8 = 2.04 g’s.

Then you’re supposed to comment on the medical consequences of that many g’s.

C) d = (1/2)at^2

## Where do i find a purple scrapbook album?

I would like an 8.5 x10 or 8×8 not top loading with the screws. Im looking for the type of album that creative memories makes. It needs to be a dark pruple.

I don’t think I’ve ever seen a dark purple scrapbook. If you’ve already tried Hobby Lobby and Michaels, find a Scrapbook store locally and go see what they have in stock. They may be able to order a certain color for you.

Other than that, you could try using fabric paint on a light beige book. Get a large bottle and use a wide natural brush and brush it on lightly until you have the shade you want. Test the color on something else first to see how it dries.

## How do people find a good friendly fish keeping forum?

I own a forum http://tropicalfishforums.x10.mx/smf/index.php and would be interested how folks find these on the net when im not listed in Google or Yahoo search engines.

Recommendations ,word of mouth finding you by chance by typing in something else .
You should list yourself on google and yahoo search pages nice site i am a member of the monster fish keepers but the site you have looks well presented and set up.
