Question

A bird has an initial position of -42.4 m and undergoes displacement of -23.2 m what is its final position

Answer 1

The final position is equal to:

$$x = x_0+d$$

where $x_0 = -42.4m$ is the initial position and $d = -23.2m$ is the displacement. Thus:

$$x = -42.4m - 23.2m = -65.6m$$

Answer. -65.6 m.
