A cook holds a $1\mathrm{.}43-kg$ carton of milk at arm's length $($see the figure below$).$ What force vec$(F{)}_B$ must be exerted by the picens.muscle? $($Ignore the weight of the forearm. Give the magnitude.$)$

Enter a number. e differs from the correct answer by more than $10\%.$ Double check your calculations. N

$($i$)$

An arm is extending horizontally to the left with a cutout that shows muscles in the upper arm. A carton of milk is in the hand, and an arrow labeled vector $F_g$ points directly downward. A point on the person's forearm lies a horizontal distance of $25\mathrm{.}0$ cm to the right of the milk and a horizontal distance of $8\mathrm{.}00$ cm to the left of the elbow. An arrow labeled vector $F_B$ points from this point up and to the right at an angle of $75\mathrm{.}0$ from the vertical.
