ChevyBoy95 Posted November 5, 2012 Report Share Posted November 5, 2012 need a little help. h(t) = v0 * t * sin(theta) - 1/2 * g * t^2 v(t) = sqrt( v0^2 - 2 * v0 * g * t * sin(theta) + g^2 * t^2) x(t) = v0* t * cos(theta) i need these as functions of time or t.

Chris Hammer Posted November 5, 2012 Report Share Posted November 5, 2012 I know squat about physics..but if these are just math equations you are just looking for (f)t = insert equation here right??

ChevyBoy95 Posted November 5, 2012 Author Report Share Posted November 5, 2012 i have v0, theta, but no time is given. i need the max height without a value for time. this iirc involves getting the derivative of the formulas which im lost on how to do. i know how to derive, but in cal 2 we dont apply them to physics so i am unsure and there is no room for error since im writing a matlab script utilizing these formulas. to get the number/function i need, i need their derivatives set to equal zero, but im unsure of how to derive them like i said.

Chris Hammer Posted November 5, 2012 Report Share Posted November 5, 2012 i think so. i have v0, theta, but no time is given. i need the max height without a value for time. this iirc involves getting the derivative of the formulas which im lost on how to do. i know how to derive, but in cal 2 we dont apply them to physics so i am unsure and there is no room for error since im writing a matlab script utilizing these formulas. I feel like this mouse after reading your reply.......... lol I haven't been in a math classes in several years..although I went through Calc and Stats I guess its all lost to me now. Sorry if I got your hopes up..i honestly was going to try and help..but realized this shit just went way over my head when I went to look some of it up and refresh my memory.

ChevyBoy95 Posted November 5, 2012 Author Report Share Posted November 5, 2012 got one. h = (v0^2*sin(theta)^2)/(2*g) Best Score to Date : 160.5 dB Outlaw (47Hz)[4 XM 15's & 2 Taramps Bass 12k's] BL : http://www.stevemeadedesigns.com/board/topic/147800-chevyboy95s-4-15s-7krms-wall-1533-db-on-half-power/YouTube: http://www.youtube.com/hitemwiththeflex/ Link to comment Share on other sites More sharing options...
Chris Hammer Posted November 5, 2012 Report Share Posted November 5, 2012 got one. h = (v0^2*sin(theta)^2)/(2*g) From what Im reading on there and doing it in my head it looks right.

ChevyBoy95 Posted November 5, 2012 Author Report Share Posted November 5, 2012 come one, someone here has to know some physics. I just havent taken it yet, but my class uses phyiscs and doesnt have it as a pre req.

DubNDodge Posted November 5, 2012 Report Share Posted November 5, 2012 Taking (highschool, not a bs course) physics right now. I could comprehend half of what was going on. v0, what was that supposed to be? where h and v height and velocity or not?
