Oh. That makes a lot of sense, thanks. How would I use that to get to T(t) though?

That's part that's confusing... if there's only a force radially, θ''(t) should be zero. However, intuitively, as the radius gets shorter the particle should start rotating faster (cons. of ang. mom.) As far as aθ goes, I'm not exactly sure what the expression should be because I can't identify...

Homework Statement [/B] A particle of mass m slides (both sideways and radially) on a smooth frictionless horizontal table. It is attached to a cord that is being pulled downwards at a prescribed constant speed v by a force T (T may be varying) Use F=ma in polar coordinates to derive an...
