Can you please work this problem out the way its described in the problem and using the units kg and cm $($Like the problem asks$)$ rather than in Newtons and Meters?

Calculate the magnitude of the resultant joint force at L$5/$S$1$ joint for the stoop lift. The worker has a height of $2\mathrm{.}0$ meters and a mass of $88$ kg $.$ The box has a mass of $10$ kg $.$

$-$ Assume that the back extensor muscle $($F$\_$m$)$ has a line of action parallel to and $5$ cm posterior $($on the back side$)$ to the trunk.

$-$ Assume the hands are at the center of the box.

$-$ Use the following masses and center of mass $($COM$)$ locations to calculate the moment at the L$5/$S$1$ joint

$-$ Note: the body masses and COM positions for the parts of the body are not in kg or cm $.$ They are $\backslash \%$ of the whole body mass$/\backslash \%$ away from L$5/$S$1$ joint. You need to convert these percentages to kg and cm $.$

$-$ For example, to find body mass for the trunk, you use Worker Body Mass $*\backslash \%$ of body mass $($for trunk$)$

$-$ To find COM position, you take $($length of trunk $*\backslash \%$ length from major joint$)$

$-$ Only consider the FBD and forces for one arm. Assume each arm holds half of the box weight mentioned above

Length of the trunk is $0\mathrm{.}52$ m

Length of the upper arm is $0\mathrm{.}33$ m

Length of the forearm is $0\mathrm{.}26$ m

Answer the questions on the following page

$1.$ Draw a FBD to solve this problem $-$ consider one arm only

$2.$ Find the COM distances $(\backslash ($ x $\backslash )$ distances only$)$ for

a$.$ Trunk

b$.$ Upper arm

c$.$ Lower$/$forearm arm

$3.$ Find the masses of the

a$.$ Trunk

b$.$ Upper arm

c$.$ Lower$/$forearm arm

$4.$ Calculate the back extensor muscle force $(\backslash (\backslash$mathrm$\{$F$\}\_\{-\}\backslash$mathrm$\{$m$\}\backslash ))$

$5.$ Calculate the resultant joint force for the L$5/$S$1$ joint $($F$\_$B$).$

a$.$ To find the results form, find the x and y components of the reaction force at the L$5/$S$1$ and use the equation
