function[h]=projecile(v_mag,theta)
%help file for projectike
%this creates position of projectile using initial velocity and angle
%gives back the height of the object 2.37m for x

%calculate velocity in x direction with vx=cos(theta)*v_initial
vx= v_mag*abs(cosd(theta));
%calculate time until dart reaches x=2.37 where the board is located
%using x=vx*t <-> t=x/vx

%calculate velocity in y direction with vy=sin(theta)*v_initial
vy=v_mag*sind(theta);
%calculate the height of the dart at time t when it reaches the board

xdis= linspace(0,2.37,100);
time=linspace(0,(2.37)/(vx),100);
ydis=1.72+(vy*time)-(0.5*9.81*time.^2);
time_=(2.37)/(vx);
h= 1.72+(vy*time_)-(0.5*9.81*time_^2);
