Two knights on horseback start from rest 88.0 m apart and ride directly toward each other to do battle. Sir George's acceleration has a magnitude of .300 m/s^2, while Sir Alfred's has a magnitude of .200 m/s^2. Relative to sir Ggeorge's starting point, where do the knights collide?

Answer 1

.150t^2 + .100t^2 = 88.0

the two distances are in the ratio 3:2

so, ...
