Find average velocity of Vector A and B

Click For Summary
SUMMARY

The discussion focuses on calculating the average velocity of two vectors, A and B, with specific initial conditions. Vector A has an initial velocity of 2 m/s at an angle of 60 degrees, while Vector B has a final velocity of 5 m/s at an angle of 330 degrees, over a time period of 5 seconds. The average acceleration formula, a(avg) = (B - A)/t, is suggested for determining the average velocity, indicating that the vectors are treated as perpendicular for this calculation.

Homework Statement



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.

Homework Equations





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.
 
Thanks! I will try that! :)
