A string is wrapped tightly around a fixed pulley that has a moment of inertia of 0.0352 kg ? m2 and a radius of 12.5 cm. An object of mass of 423 g is attached to the free end of the string
With the string vertical and taut, the object is gently released so it can descend doe to the gravitational force exerted on it by Earth. As the object descends, the string unwinds and causes the pulley to rotate, but does not slip on the pulley. What is the speed of the object after it has fallen through 1.25 m? A) 2.00 m/s B) 2.28 m/s C) 1.97 m/s D) 3.94 m/s E) 4.95 m/s
