Finding Velocity


P=# bags of powder


F=Force in N per 1 bag powder


B=Mass of Ball in kg


L=Length of cannon barrel


PF √ ( 2BL ) = Vf


B ( PF )


Finding Firing Angle


D=Distance to target


Θ=Firing Angle


D(9.81) = sin2Θ --after you get the left side, take the sin-1 of it and divide by 2.


Vf 2 You can also take 90 - Θ (the above line is Θ) as another solution


Checking if it Hit Wall/Ceiling


W=Distance to Wall


H=Height of Wall/Ceiling from ground


WVf sin Θ - 4.9 ( W )2 > H


Vf cos Θ ( Vf cos Θ )


The left side should be greater than H if the object needs to fly over an object.


It needs to be less than H if the object needs to fly under an object.
