**drwls**, Monday, October 3, 2011 at 5:29amThe space between the knights diminishes at a rate 0.530 m/s^2

Collision occurs when

(1/2)*0.530 t^2 = 72.6 m

t^2 = 274

t = 16.55 s

George will have moved

(1/2)*0.280*t^2 = 38.35 m

from his initial position at that time -- a bit more than half the initial separation.
