【1 】As shown in Figure 1, here ame an object Aof mass AZ B ofmass 7 and Cof mass r On a smooth and horizontal surfce. A and B mre inlerconnected by a spring. The Spring has the naumi lcngth of / and a spring constant た A。 B, and C are on one straight Hime and can move along the stmight line. Tuke the right direction as positive fbr velocity Neglect the mass of the spring and air resistanee 国1に示すように, 水平でなめらかな台の上に質量 /の2つの物体 A, Bと質 基wの物体Cが静止している、A と Bはばね定数たで自然散7 のばねで結ばれ てでいるAB,Cは一直線上にあり, この直線上のを動くものとする. 速度の 向きは図の右向きを正にとるものとする. ばねの質基と空気抵抗は無視できる. (①) A and B are oscillated symmetically so ss for center of mass of A and B imtereonnccted by a spdng to be fixed. Find 7, the Gimc pcriod of the oscillgtion. ばねで千ばれた A と B の重心動かないように, A とB の重心に関して左右対 -称に振動させた場合の周期了を求めよ. Next A and B are atrest. The length of the spring is the natural length / で moving speed yo collides perfect-elastically with A.
