Question $1(1$ point$)$

The net force is the vector sum of all of the forces acting upon an object. What is the

magnitude of the net force acting upon a Jenga tower being toppled by the following

pair of forces:

vec$($F$)\_($A$)=$F$\_($Ax$)$hat$($i$)+$F$\_($Ay$)$hat$($j$)$

vec$($F$)\_($B$)=$F$\_($Bx$)$hat$($i$)+$F$\_($By$)$hat$($j$)$

where F$\_($Ax$)=4\mathrm{.}0$ newtons, F$\_($Ay$)=1\mathrm{.}5$ newtons, F$\_($Bx$)=0\mathrm{.}4$ newtons, and F$\_($By$)=$

$-0\mathrm{.}5$ newtons?
