某同学在“研究小车的加速度与质量关系“的探究实验中,使用的装置如图所示.他将光电门固定在光滑水平轨道上的某点B,用同一重物拉不同质量的小车,每次小车都从同一位置A由静止释放.

(1)若遮光板的宽度d=1.2cm.实验时将小车从图示位置由静止释放,由数字计时器读出遮光条通过光电门的时间△t=4.0×10-2s,则小车经过光电门时的瞬时速度为______m/s;

(2)若再用米尺测量出光电门到小车出发点之间的距离为s,则计算小车加速度大小的表达式为a=______(各量均用字母表示);

(3)实验中可近似认为细线对小车的拉力与重物重力大小相等,则重物的质量m与小车的质量M间应满足的关系为______;

(4)测出对应不同质量的小车上遮光板通过光电门的时间△t,然后经过数据分析得出(△t)2与小车的质量M成正比.则能得出的结论是______.
