In the figure, two blocks, of masses 2.00 kg and 3 kg , are connected by a light string that passes over a frictionless pulley of the moment of inertia 0.00400 \( \mathrm{kg} \cdot \mathrm{m}^{2} \) and radius 5.00 cm . The coefficient of friction for the tabletop is 0.2 . The blocks are released from rest. Using energy methods, find the speed of the upper block just as it has moved 1 m . (answer in \( \mathrm{m} / \mathrm{s} \) )
