The momentum of an object and its change in momentum during a time interval are shown

below.

vec$(p{)}_i$

$vec(p)$

Move the $vec(p)$ arrow below as needed, then move the vec$(p{)}_f$ arrow such that it represents the

momentum of the object at the end of the time interval. Note that the three vectors are

actually co$-$linear, but the arrows below are at different heights so that they can be viewed

without any overlapping. The dotted segments are guides for aligning the ends of the arrows.
