Do you still need help with this? If i understand correctly ... ur calculations would be the same if the mass was at the intersect of the two strings. and there would be two separate tensions in the angled string. Take T_{1} as the tension in the string that is at an angle θ to the horizontal...

Force being conserved is not a rule xD Energy is conserved. If the string is placed at an angle, the weight will no longer be stationary and neither will it have a constant speed, so it is accelerating. you can no longer equate forces in a plane to 0.

I haven't studied this yet but I'll give it a shot Using L=rmv you can work out \frac{dv}{dr}, since L and m are constants. Using that equation and a given rate of change of the radius (\frac{dr}{dt}) you can work out \frac{dv}{dt}. :) Edit: As for your other questions ... idk what torque...

O .. i was pretty sure you could separate the i and j components. but a problem occurs when u is a large positivehere is part of my update method now when there are no other forces on the object: if (velo.i != 0) { loc.i += (float) (Math.log(1 - dragConst * delta * velo.i) / dragConst); velo.i...

I forgot u was a constant :P ok so: \int^{x}_{x_{0}}1\;dx=\int^{t}_{0}\frac{1}{\frac{1}{u} - kt}dt x-x_{0} = -\frac{1}{k}\;[\;ln|\frac{1}{u} - kt|\;]^{t}_{0} = -\frac{1}{k}(\;ln|\frac{1}{u} - kt|\; - \;ln|\frac{1}{u}|\;) = -\frac{1}{k}\;ln|1-ktu| so I'm guessing i do this separately...

(this is all in context to a java 2d object and is not homework related) I have an object with velocity v and position x. Its acceleration is directly proportional to velocity squared ie a=k v^{2}. Given the objects initial velocity u and its initial position x_{0} how would i work out its...

Not all (sound) waves are sinusoidal Look up waveforms
