: : : and d2T/dt2 (second derivative) will give agular acceleration.

: don't bother.
: I am just giving hints for this fellows question at hand. And as this problem was set up in R2, my hints were in relation to his specific problem and that type of coordinate plane.
sorry, I didn't mean to sound so 'arrogant'. I just meant, don't bother on my account as I was just giving some basic hints for the problem at hand...
