The equation you used first were the easy way to start. if you follow your steps again you should find that the initial velocity is 54.07m/s. for the quadratic equation you need to used the initial speed not the final. X-Xo = Vo*t + (1/2)*a*t^2. also you are applying the quadratic...

The velocity of the masses depends only on the phi component since theta is not changing nor anything else!. therefor your dphi/dt is the same for both masses. your only problem in the potential is to find how the vertical component of the rod lengths are changing as phi changes. this can be...

do you mean at the center the vector is zero inside the loop. or only for two sides that are parallel to the x axis.

how could a current in a square loop has a vector potential be zero due to 2 sides only.
