【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.

Coming up with a single definition to satisfy everyone then is Hikely a_futile task But with that said, there are certainly some commonalities from person to person and some things we can agree on。 And perhaps if we look at the sum_of these sy-thenwye_can_eome up with something at least approachingx&niversal 'definition'for success. ーーニニーーニーニーニーニービン To many of us, success means career success and financial success. you subscribe to that point of view, then success w骨 mean making alot of money positioning yourself such that you hold a lot of power and holding lots of responsibihity。 Tf we were to visualize success, then it might look like :omeone standing in an office in a Dighrrie Dlck of flts。with their hands on their hips wearing an expensive suit and 1ooking out over the city。 Only this person might be very unhappy。Tf they spend all their ime working and had to sacrifice their relationships tO get 間Se then they might be lonely and to someone else, success 本 3 TRI 9 success means being a family man/woman and getting lots of time to spend ith the children, while living in a home that you love。 Cess. one iS 。 accurate?
