To find the magnitude of the normal force, you must express F_n in terms of F_w since F_f is an unknown. Using the equations you found in the two previous parts, find an expression for F_n involving F_w and theta but not F_f.
{\cos}{\theta}F_{f}-{\sin}{\theta}F _{n} =0
F_{f}{\sin}{\theta}+F_{n}{\cos}{\th eta}-F_{w} =0

Aprisoner is forced to go into one of three rooms, but he can choose which room. the first room is ablaze with fire. the second one is rigged with explosives that will go off as soon as he enters. the third contains a pair of lions who haven't eaten in years. which room should he choose to survive?

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).

Aspacecraft that renters the earth’s atmosphere drastically slows down. the amount of kinetic energy the spacecraft has as it reenters the earths atmosphere
