Question
Two objects are connected to a pulley and a
rope as shown below. Object A has a mass of
2 kg and Object B has a mass of 4 kg. The
coefficient of dynamic friction between object
A and the horizontal plane is 0.28. Find the
downward displacement of object B until
object A starts at rest and the velocity
reaches 4 m/s.
(Ignore the friction between the pulley and the
rope.)
