A string is wrapped tightly around a fixed pulley that has a moment of inertia of 0.0352 kg m^2 and a radius of 12.5 cm. a mass of 423 g is attached to the free end of the string. With the string vertical and taut, the mass is released so it can descend under the influence of gravity. Asthe mass descends, the string unwinds and causes the pulley to rotate. What is the speed of the mass after it has fallen through 1.25 m?

A 2.00 m/s

b 2.28 m/s

C 1.97 m/s

D 4.95 m/s

E none of the above
