yay! thank you! this is the first time all year i know what i am doing

Homework Statement A child throws, at 10 m/s, a 3.4 KG package, horizontally, from a boat. The boat weighs 60 kg and the child weights 20 kg. If the boat was initially at rest, what was it's speed, after the throw? Homework Equations mv+mv=mv+mv The Attempt at a Solution I am...

I am not sure if I am doing this question right. A 10g bullet, traveling at 400 m/s hits a block of wood & emerges going at 350 m/s. How fast goes the block of wood move after being hit? Is this the right way to solve it?: mv of the bullet + mv of the block = mv' of the bullet + mv' of...

how does belvedere ?

yeah now i do see the problem with that one

I still have no clue about the other ones

i don't have a book but i know what ur saying dontdisturbmycircles i guess. and chroot. I sort of understand, but like... so the energy from the water is being transferred into wheel... to turn but the wheel is pushing the water too. But I guess a lot of the energy from the water turning the...

we just took a test on that today (one i failed btw but none the less...) you can't destroy or create energy but I don't see how that has to do with the waterfall being all weird and not making sense how it falls...

Well I am thinking its both considering everything with mass has gravity. But ofcourse the Earth has a lot more mass. I didnt even look at the picture that way. I guess I get the point but I don't know what law that would pertain to or how to put it into the words. The best I can come up with is...

lol I am in 11th grade 7 honors physics! I know that its not possible but I don't know why. I can't just say gravity lol but that's the only thing I can think of.

yeah, its a homework problem. i really have no idea because i pretty much don't really know any laws...

Why are the drawings http://britton.disted.camosun.bc.ca/escher/ascending_and_descending.jpg" breaking the laws of physics? Which laws and equations are they violating?
