Question $3(1$ point$)$

A Displacement vector describes how far and in what direction an object must go to

reach a final position from an initial position, and is the vector difference between

those positions.

Displacement $=\backslash$Delta vec$($r$)=$vec$($r$)\_($f$)-$vec$($r$)\_($i$)$

Supposing that vec$($r$)\_($f$)=-5\mathrm{.}00$hat$($i$)+7\mathrm{.}50$hat$($j$)$ and vec$($r$)\_($i$)=4\mathrm{.}00$hat$($i$)+2\mathrm{.}00$hat$($j$),$ what is the

magnitude of the displacement?
