Answer to Question #40969 in Mechanics | Relativity for alzahra

Question

A block of mass m rests on a rough plane inclined at an angle 1 as shown. A force F is
applied to the block at an angle 2 (measured from the incline plane)

a) If m = 0.1 kg, F = 0.5 N, 2=600, and 1=250, draw
a free-body-diagram showing all forces acting on the mass m
and find the static frictional force, fs, needed to prevent the
0.1 kg from sliding down the inclined plane.

b) If s= 0.36, what should be the fraction of fs found in part a to that of (fs)max, (Hint
find fs/(fs)max). Comment on the answer.
