Question

which vector has a y - component with a length of 1? a. $vec{c}$ b. $vec{b}$ c. $vec{d}$ d. $vec{a}$

Explanation:

Step1: Analyze y - component of vectors

Count grid - squares along y - axis for each vector.

Step2: Check vector a

Vector $\vec{a}$ has a y - component length of 1.

Step3: Check vector b

Vector $\vec{b}$ has a negative y - component length greater than 1.

Step4: Check vector c

Vector $\vec{c}$ has a negative y - component length less than 1.

Step5: Check vector d

Vector $\vec{d}$ has a y - component length greater than 1.

Answer:

D. $\vec{a}$
