In an historical movie, two knights on horseback start from rest 88.7 m apart and ride directly toward each other to do battle. Sir George's acceleration has a magnitude of 0.386 m/s2, while Sir Alfred's has a magnitude of 0.359 m/s2. Relative to Sir George's starting point, where do the knights collide?

  1. 1/2 (.386)t^2 + 1/2 (.359)t^2 = 88.7
    .745t^2 = 177.4
    t = 15.43 seconds to impact

    so, George rode .5(.386)(15.43^2) = 45.95 m
