I have a problem asking me to find the acceleration of a particle when its(adsbygoogle = window.adsbygoogle || []).push({});

[tex]v_i = (3.00 \hat{i} -2.00 \hat{j} ) m/s [/tex]

and then 3 seconds later,

[tex]v = (9.00 \hat{i} + 7.00 \hat{j} ) m/s [/tex]

The big problem here is that my book doesn't say anything whatsoever about getting an acceleration when dealing with unit vectors. The only thing it says about acceleration at all is that a=dv/dt, but taking the derivatives of those velocities doesn't really get me anywhere.

Help?! This is a major bottle-neck in my homework and my book is totally worthless.
