I have a problem and I can't solve it. Do I have enough info?
Two knights on horseback start from rest 88.0m apart and ride directly toward each other to do battle. Horse A accelleration has a magnitude of 0.300 m/s^2, while Horse B has a magnitude of 0.200 m/s^2. Relative to Horse A's starting proint, where do the horses collide? I am not sure what to do here. Can you tell me what formula or formulas I need to use to figure this out. Just a work question and have no clue. Do I have enough info tho?? Please let me know ASAP, thanks for looking and helping if you do. Joanne This is what I came up with, but not sure, still can't get the answer. of 52.8m

This one appears to not have enough knowns to deal with, but look closer.
Your equations would be: d = 1/2at^2+v_{o}t v = v_{o} + at If the riders start at from 0, that gives you v_{o}=0. Does that help?
