: : and d2T/dt2 (second derivative) will give agular acceleration.
: One needs to be careful here. You are correct for circular motion with
: your second derivative for the angular acceleration, but this is not
: true in a general case. The root of the problem comes from the fact
: that the unit vectors in polar coordinates are a function of
: position. If I have time this weekend I'll try to put together a
: complete explanation.
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.
