5.C【解析】物体A、B在N或N'时,A、B之间的摩擦力最大,把A、B作为一个整体进行分析,根据牛顿第二定律可得kx=3m1a,对A进行受力分析可得F=m1a,又由于F1≤/mg,解得≥3,A错误;从N到O31g的过程中,对A、B和弹簧组成的系统进行分析,根据功能关系可得E,?(m1 2m1)va,对物体B进行分析,根据动能定理可得Ep W=2×2m;,解得E,B错误;当A、B运动到O点时,A、B的速度3最大时,把A拿走,系统的机械能将减小,弹簧的最大弹性势能将减小,振幅将减小,C正确;当A、B运动到N点时,若把A拿走,系统的机械能不变,振幅不变,在振动过程中的某一位置,拿走A后.质量将减小,加速度变大,振动的周期将减小,D错误。故选C
