    Finding Roots of Functions with Matlab

    Homework Statement I need to find the roots of some functions using the bisection method, secant method, etc in Matlab. I have the m-files written, but I'm having trouble putting the function F(x)=e^{-0.5x}(4-x)-2 into Matlab. I had no problem with F(x)=0.95x^{3}-5.9x^{2}-6 but I don't...

    Angular velocity and acceleration for catapult arm

    it is mounted directly to the arm. We had a sling at first, but it was inconsistent. We're firing a washer into a plastic cup 3 m away, and the sling was hard to adjust to make the washer hit the target. The rotational inertia of the washer is I = 6.47e-6 kg*m^2 since the OD is .035 m and the...

    Angular velocity and acceleration for catapult arm

    Homework Statement This isn't a homework problem, but I'm trying to do the calculations for a catapult I built to see if its actual performance matches the theoretical performance. I'm stuck trying to map the trajectory of the projectile. Here is the picture for reference...
