1 （20分）下图是放置在竖直平面内游戏滑轨的模拟装置的示意图。滑轨由四部分粗细均匀的金属杆组成，其中水平直轨AB与倾斜直轨CD的长度均为L=3m，圆弧形轨道AQC和BPD均光滑，AQC的半径为r=1m，AB、CD与两圆弧形轨道相切，O 2D、O 1C与竖直方向的夹角均为q=37°。现有一质量为m=1kg的滑块（可视为质点）穿在滑轨上，以v 0 =5m/s的初速度从B点开始水平向左运动，滑块与两段直轨道间的动摩擦因数均为μ=0.2，滑块经过轨道连接处的机械能损失忽略不计。取g=10m/s 2，sin37°=0.6，求：（1）滑块第一次回到B点时的速度大小；（2）滑块第二次到达C点时的动能；（3）滑块在CD段上运动的总路程。
