The figure shows two blocks joined by a rope on each end going through a pulley. The masses of each block are as follow: m1 = 5 kg and m2 = 4 kg. The coefficient of friction is µ = 0.2. If the pulley has a radius R = 0.05 m and a mass of 2 kg,
calculate the magnitude of the acceleration of the hanging block.
determine the instantaneous speed of the hanging masses after m1 has descended a distance d = 2 m.
calculate the kinetic energy of the system after m1 has descended a distance d = 2 m.
determine the number of revolutions completed by they pulley after m1 has descended a distance d = 2 m.
calculate the angular acceleration 𝛼 of the pulley.
