arrite.. so it's the same equations as below with the help of some vector crap which i am too lazy to put up now..
but PLEASE! if you can help me out with this.. it would be ridiculously great!
thanks!

For question 1. x=x(0) + vt + 1/2at^2
from that we can get these two equations
x=0+(8.55)cos(43)t+0=13.6m, solve for t from this.
y=(h+(8.55)sin(43)t+1/2(-9.8)(t^2))=0, fill in t from above and plug it in and solve for h. Mass has no effect on how long it takes to fall.

Have class now, figure out the rest later.

haha, yea thanks! i'd get confused and i'd keep using initial overall velocity instead of the intial velocity of the the x or y direction..
thanks for the help!

and i finished the otherquestions so don't worry about it.. how are classes going for you now?.. freshman.. =)

Pretty good transferred to Carnegie Mellon taking Modern Physics, Exprimental Physics, Physical Analysis, Physics with cookies, etc. It's a ton of work and a ton of fun.
