The diameters of Pulleys A, B and C are 58 cm, 74 cm and 18 cm, respectively. The belt connecting Pul A and B has a length of 535 cm. Suppose that Pulley A is rotating at 0.91 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 535 cm long? b. How much time does it take Pulley B to make one revolution? How fast is the box ascending, i.e. what is the vertical speed of the box?
