O a. The us = 0.3 is the coefficient of kinetic friction that can be experimentally measured according to the roughness and
cleanliness of the contacting surface.
O b. The frictional force, F acts perpendicular to the contacting surfaces in a direction opposed to the motion or tendency for
motion of one surface relative to another.
O c. The crate will unstable equilibrium when the frictional force, Fattains a certain maximum value of limiting static frictional
force, Fs
O d. The crate will tend to slip when the frictional force, F may not great enough to balance applied force, P.
U e. The frictional force, Facts tangent to the contacting surfaces in a direction opposed to the motion or tendency for motion of
one surface relative to another.
U f. The limiting static frictional force, Fs is inversely proportional to the normal force, N.
g. The crate will tend to slip when the frictional force, F may great enough to balance applied force, P.
O h. Friction is a force that resists the movement of two contacting surfaces that slide relative to one another.
O i. The limiting static frictional force, Fs is directly proportional to the normal force, N.
j.
