    Projectile angle that considers canon length

    I tried the problem a few more times; but, ultimately I ended up with a 4th degree polynomial. I reached out to a physics professor and he was kind enough to share that a general solution would be very complicated and that simplifying via approximation would give a reasonable result. Recall...

    Projectile angle that considers canon length

    Tnx for looking at this... You are right, I can determine V_0 at the exit with a few experiments. I also know the distance to target (cup) from base of my canon (determined with sensors). I certainly understand what you mean by the symmetry of velocity and angle at (x2,y2). I'm not sure how to...

    Understanding Ax = x cos(angle) and Ay = y sin(angle) in Physics

    If your question is related to basic trig: Given a right triangle... sin(angle) = opposite_length / hypotenuse_length so, multiplying both side by hypotenuse_length gives us: opposite_length = hypotenuse * sin(angle) Thus, Ay = A sin(angle) Similarly, cos(angle) = adjacent /...

    Projectile angle that considers canon length

    Greetings, Most projectile problems are presented from the muzzle of a cannon; however, how do we solve the problem if the velocity is known at the muzzle; but the angle is controlled at the base of the canon. The issue is that, when the canon angle changes, so does the muzzle location! The...
