Suppose that in Figure \(11.18 r_{\mathrm{C}}=2 r_{\mathrm{B}}\).

(a) What is the ratio of the rotational velocity of \(\mathrm{B}\) to that of \(\mathrm{C}\) ?

(b) What is the ratio of the rotational inertia of \(B\) to that of \(C\) ?

Figure 11.18 When a moving puck strikes a stationary puck attached to a string, the rotational velocity of the puck on the string depends on string length. (a) A (b) Moving at speed v, puck A strikes identical, stationary pucks B and C. After collision, puck A is at rest. A&B. B A V TC (C) 1 Collision causes pucks B and C to move at same speed v but at different rotational speeds = |A/A].
