15.如图所示,蜡烛S在镜子中所成的像为S',若在像与镜子之间放置一块不透明的挡板AB,则会出现的现象是()A.像S'变亮B.像S变暗C.蜡烛S不能成像D.仍然能看到蜡烛S的像

25.(15分)如图所示,质量为M=3kg的物体A的左端为半径R=53m的14光滑圆弧,其余部分水平且粗糙,静止放在光滑水平面上.一质量为m=1kg的小物块B(可视为质点)从圆弧顶端无初速度释放,当B滑到圆弧底端时,A刚好与左侧固定挡板发生碰撞,碰撞过程无机械能损失.已知B在A水平部分运动的时间为1s,B与A水平部分的动摩擦因数=0.2,重力加速度g=10m/s^2.求(结果可用分式表示):(1)开始时物体A左端离固定挡板的距离;x=5&12mL=2m(2)物体A水平部分的长度.V。

18.(16分)如图所示、水平传送带以r=5m/s的速度顺时针转动、其左端A点和右端B点分别与两个水平台面平滑对接,4B长为L=5m。,左边光滑水平台面上有一被压缩的弹簧,弹簧的左端固定,右端与一质量为m=1kg的物块相连(物块与弹簧不拴接,滑上传送带前已经脱离弹簧),右边粗糙水平台面BC长s=1.5m,.它与物块间的动摩擦因数1=0.3,、在C点右侧有一半径为R的光滑竖直圆弧轨道与BC平滑连接,圆弧对应的圆心角为=120^,,在圆弧的最高点F处有一固定挡板(未画出)、物块撞上挡板后会以原速率反弹回来。当弹簧储存的弹性势能Ep=18J全部释放时,物块通过传送带的过程中,传送带运动的路程是物块路程的1920.物块可视为质点,重力加速度g取10m/s^2(1)求物坎与传送带之间的动摩擦因数μ:(2)若物块恰好到达E点、求右侧圆弧轨道的半径R;可国速送管对(3)右侧圆弧轨道半径R与(2)问相同时、若传送带的速度大小可调,欲使物块与动的后别挡板只碰一次,且碰后在CF间不脱离轨道,求传送带速度的调节范围。
