In an historical movie, two knights on horseback start from rest 79.7 m apart and ride directly toward each other to do battle. Sir George's acceleration has a magnitude of 0.323 m/s2, while Sir Alfred's has a magnitude of 0.252 m/s2. Relative to Sir George's starting point, where do the knights collide?
79.7=d1+d2
d1= 1/2 a1 t^2
d2=1/2 a2 t^2
so d1/a1=d2/a2 remember d2=79.2-d1
then solve for d1
