PLEASE ANSWER E AND F

on the air conditioner that is directed vertically downward. In order

that the unit not crush the roof tiles, the component of the unit's

weight perpendicular to the roof cannot exceed $485N.($One

newton, or $1N,$ is the $SI$ unit of force. It is equal to $0\mathrm{.}2248lb.)($a$)$

What is the maximum allowed weight of the unit? $($b$)$ If the fasteners

fail, the unit slides $L=1\mathrm{.}60m$ along the roof before it comes to a

halt against a ledge. How much work does the weight force do on

the unit during its slide if the unit has the weight calculated in part

$($a$)?$ The work done by a force vec$(F)$ on an object that undergoes a

displacement vec$(s)$ is $W=$vec$(F)*vec(s).$

$F_x=$Fsin$()$

$F_x=$Fcos$()$

$F_y=-$Fcos$()$

$F_x=\frac{F}{sin()}$
