Process$-$Oriented Problem $08\mathrm{.}002-$ Static and dynamic friction

Skip to question

A $100$ lb force P is pushing a $5$ lb block W against the side of a wall. The coefficients of static and dynamic friction between the block and the wall are s$=0\mathrm{.}35$s$=0\mathrm{.}35$ and k$=0\mathrm{.}2$k$=0\mathrm{.}2,$ respectively.
