friction force acting on the crate?
(a) 20 N to the right.
(b) 20 N to the left.
(c) 25 N to the right.

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?
