18．(22分)质量为m＝7吨的原来静止的汽车，在F₁＝3500N牵引力的牵引下沿水平直线运动t₁＝40s，然后在F₂＝2800N牵引力的牵引下沿水平直线运动t₁＝3min，最后将牵引力撤消，汽车滑行s₃＝20m后停止，全过程共用时间t＝230s。设全过程汽车所受的摩擦阻力相同，求：

(1)牵引力撤消后，汽车滑行的加速度大小；

(2)汽车所受摩擦力F_f的大小；

(3)全过程汽车行驶的路程。

17．(10分)如图11所示的装置可以测量飞行器在竖直方向上做匀加速直线运动的加速度。该装置是在矩形箱子的上、下壁上各安装一个可以测力的传感器，分别连接两根劲度系数相同(可拉伸可压缩)的轻弹簧的一端，弹簧的另一端都固定在一个滑块上，滑块套在光滑竖直杆上。现将该装置固定在一飞行器上，传感器P在上，传感器Q在下。飞行器在地面静止时，传感器P、Q显示的弹力大小均为10N。求：

(1)滑块的质量(地面处的g＝10m/s²)

(2)若此飞行器在地面附近沿竖直方向向上加速运动时，传感器P显示的弹力大小为20N，此时飞行器的加速度多大？

16．(17分)如图10所示，皮带传动装置的两轮间距L=8m，轮半径r=0.2m，皮带呈水平方向，离地面高度H=0.8m，一物体以初速度从平台上冲上皮带，物体与皮带间动摩擦因数，(g=10m/s²)求：

(1)皮带静止时，物体平抛的水平位移多大？

(2)若皮带逆时针转动，轮子角速度为72rad/s，物体平抛的水平位移多大？

(3)若皮带顺时针转动，轮子角速度为72rad/s，物体平抛的水平位移多大？
