5.如图所示,小明设计了一个自动制动装置,A、B两物块放置在斜面上,与A相连的轻绳穿过中间有小孔的B与水平面固定的电动机相连,轻绳与B之间无力的作用,用另一根轻绳连接B,使B静止在斜面上,物块A、B与斜面间的动摩擦因数=0.5,,斜面倾角=37^。现电动机以额定功率P=16W牵引物块A,,使物块A从静止出发,以最大速度与物块B发生碰撞并粘在一起,碰撞时间极短,碰撞的瞬间电动机自动切断电源不再对A提供牵引力,运动到达斜面顶端时A、B速度刚好为零,mA=mB=0.2kg,g=10m/s^2,=0.6,=0.8下列说法正确的是()A.在电动机的牵引下,物块A的加速逐渐变大B.电动机启动后对物块A的牵引力一直不变C.物块A的最大速度20m/sD.物块B距斜面顶端的距离为0.8m
