最近我在给高二学生复习第二章直线运动时,从资料[1]上找了这样的一道习题让学生做.原题:航空母舰以一定的速度航行,以保证飞机能安全起飞.某航空母舰上的战斗机起飞时的最大加速度是a=5.0m/s2,速度须达v=50m/s才能起飞,该航空母舰甲板长L=160m,为了使飞机能安全起飞,航空母舰 Recently, when I was reviewing the second chapter of the straight-line movement for my sophomores, I took this exercise from the data [1] to get students to do it. The original question: The aircraft carrier sails at a certain speed to ensure that the aircraft can safely take off. An aircraft carrier The maximum acceleration of the fighter when taking off is a=5.0m/s2, and the speed must reach v=50m/s to take off. The aircraft carrier deck is L=160m long. In order to make the aircraft take off safely, the aircraft carrier
