Multivariable Calculus
Most probably I misunderstood the question and quite frankly I thought this might be the answer, but in the answer box it did ask for the unit vector and the speed, which confused me. (This is a problem that I have already answered rightly or wrongly).

I was asked to state as a product of speed and unit vector a mass traveling at 1000ft/sec along the vector <1,sqrt(3)>. I know that v/v gives me the unit vector, which is (1/2i, sqrt(3)/2j). Do I keep the speed as given?
