Eight 60 kg skaters join hands and skate down an ice rink at4.6m/s. Side by side; they form a line 12 m long. The skater at one end stops suddenly, and the line proceeds to rotate strictly about that skater. Discover (a) angular speed. (b) Linear speed of outermost skater, and (c) the force that should be exerted on the outermost skater.
