A block is at rest on an inclined plane whose elevation can be
varied. The coefficient of static friction is
μs= 0.36, and the coefficient of kinetic
friction is μk = 0.16. The angle of elevation θ
is increased slowly from the horizontal.
At what value of θ does the block begin to slide (in
degrees)?
What is the acceleration of the block?

In the figure, a 5.40 kg block is sent sliding up a plane
inclined at θ = 37.0° while a horizontal force
of magnitude 50.0 N acts on it. The coefficient of
kinetic friction between block and plane is 0.330. What are the
(a) magnitude and (b) direction
(up or down the plane) of the block's acceleration? The block's
initial speed is 4.30 m/s. (c) How far up the
plane does the block go? (d) When it reaches its
highest...

A block of mass m = 3.3 kg is on an inclined plane with
a coefficient of friction μ1 = 0.39, at an
initial height h = 0.53 m above the ground. The plane is
inclined at an angle θ = 44°. The block is then compressed
against a spring a distance Δx = 0.13 m from its
equilibrium point (the spring has a spring constant of
k1 = 35 N/m) and released. At the bottom of the
inclined plane...
