A blue line with 5 orange tick marks then one red tick mark then 4 orange tick marks. The number zero is above the red tick mark

Natali5045456 [20]

The total displacement of the toy car at the given positions is 0.

The given parameters;

<em>First displacement of the car, = 5 cm left</em>
<em>Second displacement of the car, = 8 cm right</em>
<em>Third displacement of the car, = 3 cm to the left</em>

The total displacement of the car is calculated as follows;

<em>Let the </em><em>left </em><em>direction be "</em><em>negative </em><em>direction"</em>
<em>Let the </em><em>right </em><em>direction be "</em><em>positive </em><em>direction"</em>

$\Delta x = - \ 5\ cm \ + \ 8 \ cm \ - \ 3 \ cm \\\\\Delta x = 0$

Thus, the total displacement of the toy car at the given positions is 0.
