... velocity of the carousel, and (b) the linear velocity of a child (Fig. 8–7a) located 2.5 m from the center, point P in Fig. 8–7b. APPROACH The angular acceleration a is constant, so we can use a = ¢v兾¢ t (Eq. 8–3a) to solve for v after a time t = 8.0 s. With this v , we determine the linear velocity ...
