3.(16分)如图所示,左右无限长的光滑水平地面上有2022个大小相同的小球排成一排,相邻小球间的间距均为L,将其从左到右依次编号。1号小球质量为m,2~2022号小球质量均为km(k为比例系数)。用一根不可伸长的轻绳拴接于1号小球,上端拴接于固定结点处,拴好后轻绳刚好竖直伸直。在轻绳旁边固定一电热丝,通电时可将轻绳瞬间烧断。将1号小球向左上方提起H高度,此时轻绳伸直,与竖直方向的夹角为,所有小球仍在同一竖直平面内,将电热丝通电后再由静止释放1号小球。所有小球之间的碰撞均为弹性正碰,重力加速度为g,不计空气阻力,忽略轻绳烧断后对小球运动的影响。(1)求1号小球释放瞬间的加速度大小;(2)求1号小球与2号小球第一次碰撞中给2号小球的冲量大小以及对2号小球做的功;(3)1、2号小球间第一次碰撞后立即给1号小球施加水平向右的恒定外力F(图中未画出),使1号小球每次碰撞前瞬间的速度都相等,直到所有小球速度第一次相等时撤去外力,求外力F的大小以及最终1号和2022号小球间的距离(小球大小忽略不计)。
