required information\na chipmunk, trying to cross a road, first moves 86.0 cm to the right,\nthen 32.0 cm to the left, then 90.0 cm to the right, and finally 310 cm\nto the left.\n\nwhat is the chipmunk’s total displacement? if the total displacement is to the right,\nenter a positive value. if the total displacement is to the left, enter a negative value.\n□ cm

Answer

Explanation:

Step1: Define right as positive

Let right = +, left = -

Step2: List all displacements

$+86.0\ \text{cm}, -32.0\ \text{cm}, +90.0\ \text{cm}, -310\ \text{cm}$

Step3: Sum all displacements

$\begin{align} \text{Total displacement} &= 86.0 - 32.0 + 90.0 - 310 \ &= 54.0 + 90.0 - 310 \ &= 144.0 - 310 \ &= -166 \end{align}$

Answer:

$-166$ cm
