63. (a) We consider conservation of angular momentum (Eq. 11-33) about the center of the rod: 21012ifLLdmvMLω=¡−+=where negative is used for “clockwise.” Item (e) in Table 11-2 and Eq. 11-21 (with r⊥= d)have also been used. This leads to d= ML2ω12mv=M(0.60 m)2(80 rad/s)12(M/3)(40 m/s)= 0.180 m . (b) Increasing
