Question 2-9: Choose from the choices below how you would find the vector representing the change in velocity Av between the times t3 and t4 (at 2 and 3 s) in the diagram above. (Hint: Remember that the change in velocity is the final velocity minus the initial velocity, and the vector difference is the same as the sum of one vector and the negative of the other vector.) V4 A V3 Δν V4 -V3 B C V4 -V3 Δν Δν B Question 2-10: Based on the direction of this vector and the direction of the positive y axis, what is the sign of the acceleration +, 0 or -? Positive Negative Zero
