36．
(18分)如图所示，竖直平面内有一宽L=1米、足够长的光滑矩形金属导轨，电阻不计．在导轨的上下边分别接有电阻R1=3Ω和R2=6Ω．在MN上方及CD下方有水平方向的匀强磁场I和II，磁感应强度大小均为B=1T．现有质量m=0.2kg、电阻r =1Ω的导体棒ab，在金属导轨上从MN上方某处由静止下落，下落过程中导体棒始终保持水平，与金属导轨接触良好．当导体棒ab下落到快要接近MN时的速度大小为v1=3m/s．不计空气阻力，g取10m/s2．
(1)求导体棒ab快要接近MN时的加速度大小．
(2)若导体棒ab进入磁场II后，棒中的电流大小始终保持不变，求磁场I和II之间的距离h．
(3)若将磁场II的CD边界略微下移，使导体棒ab刚进入磁场II时速度大小变为v2=9m/s，要使棒在外力F作用下做a=3m/s2的匀加速直线运动，求所加外力F随时间t变化的关系式．
珠海市2009－2010学年度第二学期高三质量监测
35．(18分)小明同学身高1.70m，质量为60kg，在一次跳高测试中，他先弯曲两腿向下蹲，再用力蹬地起跳，从蹬地开始经0.40s竖直跳离地面．假设他蹬地的力恒为1050N，其重心上升可视为匀变速直线运动．求小明从蹬地开始到最大高度过程中机械能的增加量．(不计空气阻力，g取10m/s2)
某同学进行了如下计算：
小明蹬地起跳的过程中，受到地面的弹力F作用，向上做匀加速直线运动．
因为地面的弹力F与蹬地的力F ′ 是作用力与反作用力，因此有
F＝F ′＝1050N ①
根据牛顿第二定律得F＝ma ②
经0.40s跳离地面时的速度v＝at ③
起跳后人做竖直上抛运动，设上升的最大高度为h，则v2－0＝2gh ④
在最高点，动能为零，故机械能的增加量为ΔE＝ΔEp＝mgh ⑤
联立以上各式即可求解．
你认为该同学的解答是否正确？如果认为正确，请求出结果；如果不正确，请作出正确解答．
