15.(18分)如图,倾角=30^的直轨道AC与光滑圆弧轨道CDEF在C处相切且平滑连接,整个装置固定在同一竖直平面内。圆弧轨道的半径为R,DF是竖直直径,O点为圆心,E、0、B三点在同一水平线上。A、F也在同一水平线上,两个小滑块P、Q(都可视为质点)的质量均为。已知滑块Q与轨道AC间存在摩擦力且动摩擦因数处处相等,但滑块P与整个轨道间和滑块0与圆弧轨道间的摩擦力都可忽略不计。同时将两个滑块P、Q分别在A、B两点由静止释放,之后P开始向下滑动,在B点与Q相碰。碰后P、Q立刻一起向下且在BC段保持匀速运动,已知P、Q每次相碰都会立刻合在一起运动但两者并不粘连,取重力加速度为g,求:(1)两滑块进入圆弧轨道运动过程中对圆弧轨道的压力的最大值;(2)Q第一次沿斜面上滑的最大距离;(3)滑块P在AC轨道上往复运动经过的总路程。
