Question
3. Two masses, 4.0 kg and 6.0 kg, are connected
by a “massless" rope over a "frictionless" pulley
as pictured in the diagram. The ramp is inclined
at 30.0° and the coefficient of kinetic friction on
the ramp is 0.18.
4.0 kg
Hx = 0.18
6.0 kg
300
a. If the rope breaks when the 4.0-kg mass
is 3.0 m from the bottom of the ramp,
how long will it take for the mass to slide
all the way down? Include a new
free-body diagram and assume the
sliding mass starts from rest.
b.
Determine the acceleration of the
system once it begins to slide.
С.
Determine the tension in the rope.
