Honors Physics

The general solution we developed was Dx = vx Dt and Dt = (vyf - vyi)/ay

and vyf = sqrt ( 2ayDy+ vyi squared)

so we have the ugly but useful:

Dx = vx [sqrt ( 2ayDy+ vyi squared)-vyi]/ay

Now rememeber that
ay =-g;
vx vicosthetaH; and
vyi = vi cos thetaV

and you are all set to solve some tough problems like those on worksheet 2.
