NerdAPult #2 – Another Projectile Motion Problem (10:30)
This time in our projectile motion problem, we know the displacement in the ydireciton and we are solving for the displacement in the xdireciton. We could you use the quadratic formula and I even show you how, however, I also show you the way I recommend doing it which avoids the quadratic formula.
