A set of reducing gears is used to raise the box as shown below. Pulleys B and C are welded together. The diameters of Pulleys A, B and C are 44 cm, 74 cm and 16 cm, respectively. The belt connecting Pulleys A and B has a length of 495 cm. Suppose that Pulley A is rotating at 0.85 revolutions per second. Answer the following, round your answers to at least 3 significant figures and include units. a) How much time does it take the belt to make one revolution if the belt is 495 cm long? b) How much time does it take Pulley B to make one revolution? c) How fast is the box ascending, i.e. what is the vertical speed of the box?
