This is Grade 11 Physics. I don't want the answer, I just want to know how to do it: Two football players separated by 42 m run directly toward each other. Football player #1 starts from rest and accelerates at 2.4 m/s2 [E], and football player #2 moves uniformly at 5.4 m/s [W]. (a) How long does it take for the players to collide? b)How far does each player move? I know I have to use on of the 5 motion equations, I just don't know which one since I have no clue on how to handle opposite motions. I've tried drawing diagrams and really want to avoid using a quadratic equation since my teacher dislikes it. Any other ways? If a quadratic equation is the easiest way to get the answer, then how would I be able to use it?
