Two masses, pulley, incline with friction: Two blocks of mass M and m are connected by a light
rope that passes over a frictionless pulley. The mass M moves down the incline, which has an angle of
inclination, as shown. The coefficient of kinetic friction between M and the incline is μ. (See PSL
5.5,7,9)
a) Draw FBDs for each mass.
b) In terms of the given symbols and any known constants (like g), solve for (i) the tension in the
rope, and (ii) the acceleration.
c) If M = 10.0 kg, m = 7.00 kg, μ = 0.200, 0 = 30.0°, what are the values of the tension and
acceleration?

Follow-up Question
Someone gives a sharp but momentary shove to the blocks, and they begin to slide. Now block A is
sliding to the right, and block B is sliding down the incline.
d) Draw new free-body diagrams. They are similar to before, but consider which forces now change
in type, magnitude, and/or direction.
e) Describe any changes in any of the forces.
f) Determine the acceleration of the system (symbols).
g) Substitute in numbers to determine the acceleration.
