Consider two masses of 4.4 kg and 7.2 kg
connected by a string passing over a pulley
having a moment of inertia 7.2 g · m2 about
its axis of rotation, as in the figure below.
The string does not slip on the pulley, and the
system is released from rest. The radius of
the pulley is 0.33 m.Find the linear speed of the masses after
the 7.2 kg mass descends through a distance
46 cm. Assume mechanical energy is conserved during the motion. The acceleration of gravity is 9.8 m/s2 .
Answer in units of m/s.
