This program creats trajectories. you input the Velocity and anlge, and it gives u max height and distance. I will post the source after i hand in my ISU, as it is employed in it. It also draws an arc, showing you it's path.

OK HERES THE CODE:
code:

%Variable Explanation:
%x = Velocity
%y = angle
%power = (Velocity = Vo)
%angle = angle
%v1 = Vxo
%v2 = Vyo
%t = time
%t2 = time / 2
%d = distance
%h = height

%Actual Program:

var x,y,velocity,angle,v1,v2,t,t2,d,h: real
put "Velocity:"
get velocity
x:=velocity
put "Angle:"
get angle
y:= angle
v1 :=x* cosd(y)
v2 :=x* sind(y)
t := (2* v2)/(9.8)
d:=v1 * t
t2:= v2 /9.8
h := v2*t2 - (0.5*(9.8 * (t2**2)))
put "Final distance: ",d
put "Max Height: ",h
Draw.Arc((d) div 2,0,(d) div 2,round(h),0,180,black)

you should all download JSBN's ISP when he posts it to see this subprogram in action... it's a well... u'll see. Rolling Eyes

its really good, but can i suggest putting in something like "max height: 2222 METERS or CENTIMETERS" or some kind of classification. same thing when asking for angle, and tragectory.otherwise really good!

why woudl you do that skatelhs? it's not like it's asking for the input velocity in meters/second or whatever


I am assuming he is just using earth's gravity of 9.8m/s^2 in his calculations ... but really that value could be anything...

yes, earth's gravity is employed. it's 9.8m/s^2

Bump.... It "bumps" the topic back to the top of the forum If i had just editied my first post, this topic, as far as i know, would still be a few pages back. So..... Yea....
