Question
Two blocks of mass ma=8.9kg and mg=8.3kg are attached to the ends of a massless string which passes through a pulley of radius R=37cm and mass M=7.1 kg. If
the coefficient of the kinetic friction between the table and ma is Hk=0.4 and mg was at an initial height of h=9.6m when the system was released from rest,
determine the angular speed of the pulley right before mg hits the ground.Express your answer using Sl units with one decimal place. Take g=9.8 m/s? and assume
that the pulley is in the shape of a disk with =MR2/2.
