在不考虑传送闪现等诸多因素的情况下,
(1)当龙龟和龙女速度相等时,距离最大。设速度相等时刻为t,则
4+0.8t=6.4-0.7t → t=1.6s,此时,
x(龙龟)=4×1.6+1/2×0.8×1.6²=7.424m,
x(龙女)=6.4×1.6-1/2×0.7×1.6²=9.344m,
∴最大距离x(max)=x(初始)+x(龙女)-x(龙龟)=9.92m
(2)v(龙龟max)=4+0.8×3=6.4m/s,t(龙女变速)=(6.4-4.3)/0.7=3s
当追赶时间t=7s时,
x(龙龟)=(4+6.4)×3/2+6.4×4=41.2m,
x(龙女)=(6.4+4.3)×3/2+4.3×4=33.25m,
此时龙龟与龙女距离差Δx=x(初始)+x(龙女)-x(龙龟)=0.05m>0
∴披甲龙龟不能追上并击杀龙血武姬
