21.如图所示,一小钢球自离地高度处从四分之一光滑圆弧轨道AB上滑下,A处切线竖直,B处切线水平.现改变圆弧轨道的半径R的大小,钢球到达B处时的速度大小为v,钢球在B处时对轨道的压力大小为F,钢球落地点距O点的距离为x,钢球落地时速度方向与水平方向,夹角的正弦值为sinθ,,则下列相关图像正确的是
7.平面上有两个相同的匀质凹槽P、Q,质量为m凹槽内有一个圆的光滑轨道.质量同为m的小球,从凹槽P的顶端由静止开始下滑,下列说法正确的是A.小球在凹槽Q上能达到的最大高度为B.小球在凹槽Q上能达到的最大高度为94C.小球从凹槽Q返回水平面的速度为gR2D.小球从凹槽Q返回水平面的速度为0A
16.(17分)如图所示,弹簧一端与一小物体相连,另一端悬挂于天花板上的点,小物体置于光滑水平面上的A点,O、A在同一竖直线上且相距L0=12cm,弹簧恰好处于原长。现对物体施加水平向右缓慢增大的拉力F,当F1=9N时物体处于与A相距9cm的B点;继续缓慢增大拉力,当物体处于与B相距7cm的C点时,小物体对水平地面的压力恰好为零。不计弹簧重力,重力加速度g取10m/s^2,弹簧始终处于弹性限度内。求:(1)弹簧的劲度系数k;(2)小物体的质量m
