SHin Figure a rope is wound around a horizontal disk (la c= 0,5 kgm²; R =20 cm), passed across a ey (lp_ou-0,2kgm and R, -8 cm), and connected to a hanging m-4 kg mass. Initially, the mass is held in place, the system is at rest. e mass is then released and descends in response to the force of gravity. The rope does not slip on the pulley or horizontal disk. Both the pulley and the disk rotate on bearings that are effectively frictionless. Find the angular speed of the pulley after the mass has descended h=120cm. Calculate the acceleration of the mass. pulley h=120 cm
