a. d1 + d2 = 30 m.
0.5a1*t^2 + 0.5a2*t^2 = 30.
0.5*0.49*t^2 + 0.5*0.43*t^2 = 30.
t = ?.
b. d1 = 0.5a1*t^2.
Two soccer players start from rest, 30 m apart. They run directly toward each other, both players accelerating. The first player’s acceleration has a magnitude of 0.49 m/s2. The second player’s acceleration has a magnitude of 0.43 m/s2. (a) How much time passes before the players collide? (b) At the instant they collide, how far has the first player run?
