comment Physics timestep questions
My code isn't using that formula. The time 't' in s=ut+0.5at^2 is the total time since the projectile launched, not the elapsed time. Similarly the 'u' is the initial velocity, not the current velocity. My code is doing Euler integration, using the elapsed time since the last frame. First it integrates the current velocity with v += at, then it integrates the position with p += vt.

comment Forces on a wire in a 2D environment? (Physics)
@Andrew - For your first point, yes, the force applied to the box by the joint is by definition equal to the tension in the wire. For your second point, you're right, this wasn't very clear, it's actually the angle between the wire and the contact point normal. I've edited the answer to make this clearer.
