The discussion revolves around a trajectory problem involving a cannon fired at a 30-degree angle. Participants are attempting to derive a relationship between muzzle velocity and distance, using various equations and expressions related to projectile motion.
The discussion is ongoing, with participants providing guidance on how to approach the problem. Some are suggesting methods to derive the range from muzzle velocity, while others are questioning the correctness of the expressions being used. There is a recognition of the need to clarify the definitions and relationships between the variables involved.
Participants are working with limited information, primarily the height of the cannon and the angle of projection. There is confusion regarding the use of certain variables and the formulation of equations, which may affect the ability to graph the desired relationship accurately.
You put this 9.8 in the wrong place. It should divide everything not just the radical.Sciencerob said:Almost there... I got it to work but when I put in 300 for Velocity I got a number around 40,000.
=(300*SIN(0.5236)+SQRT(300^2*SIN( 0.5236)*SIN(0.5236)+2*(44.1)*(9.8))/9.8)*300*COS( 0.5236)
That is my formula.
