1 在探究静摩擦力变化的规律及滑动摩擦力规律的实验中，特设计了如甲图所示的演示装置，力传感器A与计算机连接，可获得力随时间变化的规律，将力传感器固定在光滑水平桌面上，测力端通过细绳与一滑块相连（调节传感器高度可使细绳水平），滑块放在较长的小车上，小车一端连接一根轻绳并跨过光滑的轻定滑轮系一只空沙桶（调节滑轮可使桌面上部细绳水平），整个装置处于静止状态．实验开始时打开传感器同时缓慢向沙桶里倒入沙子，小车一旦运动起来，立即停止倒沙子，若力传感器采集的图象如乙图，则结合该图象，下列说法正确的是：______． A．可求出空沙桶的重力 B．可求出滑块与小车之间的滑动摩擦力的大小 C．可求出滑块与小车之间的最大静摩擦力的大小 D．可判断第50秒后小车做匀速直线运动（滑块仍在车上）
