Two pulleys have radii $$29\mathrm{cm}$$ and $$12\mathrm{cm}$$, respectively (as in Exercise 52 in Section $$3.4$$ in the Text). The larger pulley rotates 39 times in 40 seconds. Find the angular speed of the smaller pulley in radians per second. Answer: 2. Angular Speeds of Pulleys The two pulleys in the figure have radii of $$15\mathrm{cm}$$ and $$8\mathrm{cm}$$, respectively. The larger pulley rotates 25 times in $$36\sec$$. Find the angular speed of each pulley in radians per second.
