Physics

Question that will make you go crazy wanting to know the answer!?

Asked By: "josh.unknown"
This question has bothered me for about 2 months now. I've researched it and found no questions similar. Please, I want your opinion QUESTION: Say you're in a moving vehicle and you have a paper ball (or anything with little mass). There is no wind. When you stick your hand out you feel wind because you're moving. (keep in mind there is actually no wind blowing) You drop the object out the window, does it fly back from the wind created from the movement, or does it simply fall to the ground and appear to fly back only because you are moving away from it? Just tell me if you need more details.

Impulse and momentum change in two barges...?

Asked By: Anonymous
Two long barges are moving in the same direction in still water, one with a speed of 10 km/h, and the other with a speed of 20 km/h. While they are passing each other, coal is shoveled from the slower to the faster one at a rate of 1000 kg/min. How much additional force must be provided by the driving engines of (a) the fast barge, and (b) the slow barge if neither is to change speed? Assume that the shoveling is always perfectly sideways and that the frictional forces between the barges and the water do not depend on the mass of the barges. How would you get your answers? Can you explain it in detail? Good Luck! :)
