Problem $09\mathrm{.}052-$ Block over pulley $-$ DEPENDENT MULTI$-$PART PROBLEM $-$ ASSIGN ALL PARTS

A $17$ N weight $W$ is supported by a weightless cable where portion $AB$ of the cable is horizontal. The coefficients of static and kinetic friction are $0\mathrm{.}5.$

NOTE: This is a multi$-$part question. Once an answer is submitted, you will be unable to return to this part.

Problem $09\mathrm{.}052.$b $-$ Pulling force to hold hanging block

Determine the value of $P$ so that downward motion of the $17$ N weight is impending. $($Round the final answer to four decimal places.$)$

The value of $P$ is $$ N$.$
