Well I don't know how to or what an array is, but I guess I can look it up. Thanks! :) I'll fix the wrong value thing to loop until the correct value is given. Thank you again :)
Homework Statement
So, we have a project to make a tic-tac-toe game and for bonus points we can make sure the player(s) can not enter the same position more than once. I can't think of a way to do this. I'm sure I need to use a 'for loop' or a 'while loop'.

Well what I mean is, we have all kinds of formulas for rigid bodies, can we just apply them to a non-rigid or fluid body, or are there different mechanics for non-rigid/fluid bodies?
I heard a rumor from some people at a scrap yard that it's impossible to sepperate copper from stainless steel, and that the copper ruins the stainless steels structual integrety. Is there any truth to this?
So I got V=D/sqrt(2*h/g)
Then plug that into: m*g*H=1/2*m*(D/sqrt(2*h/g))^2 Since H=x+h we get
m*g*(x+h)=1/2*m*(D/sqrt(2*h/g))^2 then solve for x giving us:
x=((.25*d^2)/h)-h Does that seem correct?
I got -2.975?
Never mind I forgot to add in the mgh to the end of the equation silly me thanks...

Homework Statement
A 3.5 kg block starts at rest and slides a distance d down a frictionless 28.0° incline, where it runs into a spring. The block slides an additional 21.0 cm before it is brought to rest momentarily by compressing the spring, whose spring constant is 435 N/m.
A)What is the...
Ok. I figured it out!you add the energy from the spring and get this equation:
1/2kx^2=1/2mv^2+1/2ky^2 Where y= the distance the spring travels with the cork i.e. after the equilibrium
Then solve for v and get:
v=(√(20)*√(.082^2-.04^2))/√(.00376) and you get v=5.22 m/s.
