计算题

（19分）如图所示，一倾角为 的足够长固定光滑斜面底端有一与斜面垂直的挡板M，物块A、B之间用一与斜面平行的轻质弹簧连接且静止在斜面上。现用外力沿斜面向下缓慢推动物块B，当弹簧具有5J的弹性势能时撤去推力，释放物块B 。已知物块A、B的质量分别为5kg和10kg，弹簧的弹性势能的表达式为 ，其中弹簧的劲度系数为k=1000N/m，x为弹簧的形变量，g=10m/s2。求

（1）撤掉外力时，物块B的加速度大小；

（2）外力在推动物块B的过程中所做的功；

（3）试判断物块A能否离开挡板M？若A能离开挡板M，求出物块A刚离开挡板M时，物块B的动能；若A不能离开挡板M，求出物块A与挡板M之间的最小作用力。
