Explanation / Answer

Normal = 72 N

Force of static friction = 72*0.5 = 6 N

Force of kinetic friction = 72*0.25 = 18 N

D) when force applied is 37 N (>36 N), then it is in regime of kinetic friction

So friction force = 18 N

E) when force applied is 150 N (>36 N), then it is in regime of kinetic friction

So friction force = 18 N
