A payload B of mass mB = 50 kg is lifted via the pulley system shown by the application of a constant force F = 300 N. The pulleys are identical and can be modeled as uniform disks of radius rp = 10 cm and mass mp = 8 kg. The cord does not slip relative to the pulleys. Modeling the cord as inextensible and neglecting friction at the pulley bearings, determine the speed of B after B has been lifted a height h = 1 m from its initial rest position. Treat all cable segments as being purely vertical.
