1. A 50-N crate sits on a horizontal floor where the
coefficient of static friction between the crate and
the floor is 0.50. A 20-N force is applied to the crate
acting to the right. What is the resulting static
friction force acting on the crate?
(a) 20 N to the right.
(b) 20 N to the left.
(c) 25 N to the right.
(d) 25 N to the left.
(e) None of the above; the crate starts to move.
3. The problem that shall not be named.
m
A
(a) A block of mass m = 1 kg, sits on an incline
that has an angle 0. Find the coefficient of
static friction by analyzing the system at
imminent motion. (hint: static friction will
equal the maximum value)
(b) A block of mass m = 1kg made of a different
material, slides down an incline that has an
angle 0 = 45 degrees. If the coefficient of
kinetic friction increases is μ = 0.5 what is
the acceleration of the block?
