Two soccer players start from rest, 43 m apart. They run directly toward each other, both players accelerating. The first player's acceleration has a magnitude of 0.56 m/s2. The second player's acceleration has a magnitude of 0.47 m/s2.
(a) How much time passes before the players collide?
(b) At the instant they collide, how far has the first player run?
