Question:

An object moves along the $\backslash ($ x $\backslash )-$axis. When the object passes through $\backslash ($ x$=+1\backslash$mathrm$\{$~m$\}\backslash ),$ the object has a velocity of $\backslash (+2\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash )$ in the positive x $-$direction. When the object passes through $\backslash (\backslash$mathrm$\{$x$\}=\backslash )+2$ m $,$ the object has a velocity of $\backslash (+1\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash )$ in the positive $\backslash ($ x $\backslash )-$direction.

Select the response which best describes the average acceleration of the object between the two points.

Select one from the below options:

A$.$ The object's average acceleration is zero.

B$.$ The object's average acceleration is in the positive x $-$direction.

C$.$ The object's average acceleration is in the negative $\backslash ($ x $\backslash )-$direction.
