12.(2009·上海宝山区)A、B两位同学在某游览区的同一个站点分乘甲、乙两辆车去不同的景点游玩,A乘坐的甲车先出发,当后出发的乙车已经以速度v0匀速行驶时,乙车上的B同学发现自己和A同学互相错拿了双方外型相同的旅行包,在B正欲与A联系时,看到了因途中停车的甲车恰在同一条路上的前方离乙车x处向前启动,于是打算与A相遇时交换旅行包.若甲车启动后先以加速度a作匀加速直线运动,待速度达到v0后做匀速直线运动,且假定出发站点和两景点站都在同一条平直公路上,出发站点离两景点都足够远,两车只要相遇两位同学就可以交换旅行包.已知x<,请你分析两位同学在途中能否交换旅行包?(车身长度不考虑)
某同学是这样分析的:设甲车启动后经时间t两车相距Δx,则Δx=at2+x-v0t=a(t-)2+x-,只有当x-=0,且t-=0时,Δx=0,此时两车才可能相遇,但x<,所以两位同学在途中不能交换旅行包
你觉得他的分析是否正确?如认为是正确的,求出两车相距的最近距离;若认为是不正确的,则说明理由,并求出从甲车开始启动到两同学交换旅行包的时间.
解析 因为对于Δx=at2+x-v0t,并不需要x-=0与t-=0同时成立时,才有Δx=0.
对Δx=at2+x-v0t,若令Δx=0
则有at2-2v0t+2x=0,解得
t==±
因为x<,即4v-8ax>0,故t有解,所以两位同学在途中能交换旅行包.
又因为只有当甲车达到速度v0前两车才可能相遇,故t<
所以从甲车开始启动到两同学交换旅行包的时间为:
t=-.
