Find average velocity of Vector A and B

  1. Sep 11, 2009 #1
    1. The problem statement, all variables and given/known data

    Arrow 'A" is at an angle of 60 degress and V(initial)= 2 m/s. Arrow B is pointed at 330 degrees with V(final) of 5 m/s. Time= 5 seconds. What is the A(avg) vector is the question.

    2. Relevant equations

    3. The attempt at a solution

    I am at a total loss............... I know how to ADD vectors - how to get their direction - but the teacher just threw this question at us, and I can't find any help in book either...........

    Do you mean A(avg) is average acceleration? In that case
    a(avg) = (B - A)/t
    Since A and B are perpendicular to each other A + B and B - A are the same.
