Hello there,
So I'm trying to graph the traajectory of an object based on the user input (initial height, angle of elivation, initial velocity of object...etc)
I got kinda stuck and would really appreaciate any help or advice.
Thanks,
Ben N.

What have you done so far? What specific problems are you having with your code?

I was just having a problem figuring out hte equation, it's been a while since physics.

If you have the equations and don't have to process any differential equations it is as easy as:
t=0:.01:14;%seconds
height=10;%meters
angle=45;
v=100;%m/s
a=-9.81;%m/s^2
y=@(t).5*a*t.^2+v*sind(angle)*t+height;
x=@(t)v*cosd(angle)*t;
plot(x(t),y(t));
