Answer:
[tex]F=-88Ib[/tex]
Explanation:
From the question we are told that:
Force P=88Ib
Mass of crate M_c=210Ib
Generally the equation for Frictional force F is mathematically given by
[tex]Friction\ force (f) = friction\ coefficient\ (u) * Normal\ reaction (N)[/tex]
[tex]F=u*N[/tex]
with [tex]\mu =0.47[/tex]
[tex]F=98.7Ib[/tex]
Therefore since Static Friction supersedes applied force body remains at rest.
Frictional force =88Ib (negative)
[tex]F=-88Ib[/tex]
