[问答题]
A uniform rod of mass M and length6e -0,aewtloj;0 9e,ujmvp8 laarp5z L can pivot freely (i.e., we ignore frictias6 /9ea;gn1k5s7 rhl; buwrst*m2u von) about a hinge attached to a wall, as in Fig. 8–54. The rub;wre shkm 57rs926n uat1*;ls/ a vgod is held horizontally and then released. At the moment of release, determine (a) the angular acceleration of the rod, and (b) the linear acceleration of the tip of the rod. Assume that the force of gravity acts at the center of mass of the rod, as shown. [Hint: See Fig. 8–21g.]
