+244 Two steel blocks are connected by a light string that passes over a frictionless pulley with a moment of inertia of 0.0030 kg ∙ m2 and diameter 5 cm. The coefficient of kinetic friction between the table top and the upper block is 0.25. The blocks are released from rest, and the string does not slip on the pulley. How fast is the 3 kg block moving when the 2 kg one has dropped 0.50 m?
A.3.2 m/s
B.1.2 m/s
C.2.0 m/s
D.1.1 m/s
E. 5.4 m/s
