Answer:
a. F
fric
=μ
s
W=0.4∗20=8N
b. Since F
applied
<F
fric
F
fric
=5N
c. Minimum force required to start the motion F=F
staticfric
=8N
d. Minimum force required to start the motion
F=F
kineticfric
=μ
k
W=0.2∗20=4N
e. F>F
staticfric
motion started.
F>F
kineticfric
hence motion continues.
F
fric
=4N
