In a historical movie, two knights on horseback start from rest 70 m apart and ride directly toward each other to do battle. Sir George\'s accleration has a magnitude of 0.22 m/s2, while Sir Alfred\'s has a magnitude of 0.25 m/s2. How far from Sir George\'s starting point do the knights collide?

we have, 0.5 x 0.2 x t^2 + 0.5 x 0.34 x t^2 = 99 time = t = 19.148 seconds Distance = 0.5 x 0.2 x 19.148^2 = 36.67 metter
