- 弹性势能不会求…… (17) Fukuphysics 2005-07-06 15:12:27
  - Re:弹性势能不会求…… E = k * (l-s)^2 /2 (19) sunmoonstar_love 2005-07-06 15:13:17
  - 动能是W=1/2*m*v*v,重力势能=mgh，剩下的就不知道了 (0) Fukuphysics 2005-07-06 15:13:34
    - 有这些就够了，关键在判断 v 是否超过10，仔细考虑一下，再说就没意思了 (0) sunmoonstar_love 2005-07-06 15:18:25
  - 哎呀..应试教育出来的人啊 (19) uni 2005-10-04 21:09:42
终于过了，忘了考虑，l<s的情况，ft.... 要是在高中时，不到一分钟就能搞定 (0) sunmoonstar_love 2005-07-06 14:58:42
