**bobpursley**, Tuesday, September 4, 2012 at 1:21pm"product"? What does that mean in vectors?

I suspect the problem means NOT the product, but to indicate the velocity as a vector. IF so, then speed along the direction of the vector is 1000, but looking at the triangle (1,sqr3, 2) then

velocity=1000*cosTheta *i + 1000*sinTheta*j

= 500 i +866 j

velocty=500i +.573 j

**gerald**, Tuesday, September 4, 2012 at 1:29pmMost 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).
