Question

4. The blocks of ( m_{1}=10 mathrm{~kg} ) and ( m_{2}=20 mathrm{~kg} ) are connected to the end of a rope wrapped on the pulley of ( M=20 mathrm{~kg} ) and radius of ( 20 mathrm{~cm} ). The system is started from rest. a. Determine the acceleration of the block! b. Find the tension in the rope! c. Give the angular acceleration of the pulley! d. Calculate the angular speed of the pulley at ( mathrm{t}=2 mathrm{~s} ) ! e. Determine the number of revolutions were done by the pulley in ( 10 mathrm{~s} ) ?
