Has anyone ever seen an animal butchered? It must not be very pleasant thing to watch...or done it? Are slaughter houses open for group or individual tours, like bread factories or auto assembly lines? If not, where can I purchase a movie documentary of a beef slughter house, and if there are none available, why hasn't 60 Minutes done one yet? Or do you think Mickey D's would object-vociferously? I would like such a documentary to show all my caniverous friends their complicity with this viscious activity which makes men into beasts.

1. A worker pulls a sled with a force of 80 N directed at an angle of 60 degrees above the horizontal over a level distance of 6 m. If a frictional force of 24 N acts on the sled in a direction opposite to that of the worker, what net work is done on the sled?

a. 240 J, b. 216 J, c. 144 J, d. 96 J


2. A model rocket sits on the launch pad until its fuel is ignited, blasting the rocket upward. During the short time of blast-off, as the ignited fuel goes down, the rocket goes up because:

a. momentum is conserved in this process
b. the fuel pushes on the ground
c. air friction pushes on the escaping fuel
d. the downward force of gravity is less than the downward momentum of the fuel

please explain why you believe the answers are what they are just in case yours are different than mine. thanks a lot guys!

For example, say I have a pile of X checks, which can have one of a known set of costs. The average value of the checks in the pile is Y. How can I find the possible arrangements (number of checks with each known cost where a total of X checks would average Y)?

This is similar to the problem of "You have $1.34 in change and 8 coins, what coins do you have". What's the best way to solve this? (I have large X and Y.)
