Some details of the models

  1. The first model assumes vy is constant and vx is only effected by gravity
    • v0=l/mass
    • t{s}=2v0sin(θ)/g
    • h{m}=v02sin(θ)2/2.0*g
    • d{m}=v0sin(2θ)/g
  1. The second model assumes initial height might not be zero
    • vy0=v0sin(θ)
    • y0=ydiff and x0=0
    • vyn=vyn-1-gdt
    • xn=xn-1+v0cos(θ)dt
    • yn=yn-1+vyn-1dt
  1. The third assumes drag due to speed
    • D=1.2kπ0.3662
    • vx0=v0cos(θ) and vy0=v0sin(θ)
    • v=sqrt(vx2+vy2)
    • axn=-D*v*vx/mass
    • ayn=-g-D*v*vy/mass
    • vxn=vxn-1+axdt and vyn=vyn-1+aydt
    • xn=xn-1+vxn-1dt+axn-1dt2
    • yn=yn-1+vyn-1dt+ayn-1dt2
