Answer:
The y component of her velocity is zero
Explanation:
Given that North and South represent the positive and negative y component of the velocity vector.
And East and West represent the positive and negative x component of the velocity vector.
For a girl walking east at 2.7 m/s
The x component of velocity is;
vx = 2.7 m/s (east is positive x axis)
The y component of velocity is;
vy = 0 m/s (no movement in the northern and southern direction)
Therefore, The y component of her velocity is zero (0m/s)
