Homework Help: PHysics

Posted by Veronica on Tuesday, February 2, 2010 at 4:16pm.

A 3.00 kg object has a velocity (5.20 ihat - 2.40 jhat) m/s. (Note: From the definition of the dot product, v2 = vvec·vvec.)
(a) What is its kinetic energy at this time?

Could some one just please show me how to convert the velocity vector into the "regular" form?
Thank You
