Re: Help with ballistics formula  TOPIC_SOLVED

Success! With the help of my friend who is amazing in calculus and trigonometry, I have done it!(except for air friction) D=\frac{v^2\sin(2\theta)}{g} Solve for v . In this case, we will use 100 as D and \theta will be 30° 100=\frac{v^2\sin(2\theta)}{g} (9.81)100=\frac{v^2 \t...
