*36.  Two soccer players start from rest, 48 m apart. They run directly toward each other, both players accelerating. The first player’s acceleration has a magnitude of 0.50 m/s2. The second player’s acceleration has a magnitude of 0.30 m/s2. (a) How much time passes before the players collide? (b) At the instant they collide, how far has the first player run?

 

Here is what we know.  The first player (on left) has  , and   the second player (on right) has has  , and  

Basic Equation is

Each player gets one

 

 

Now plug d from player 1 into the equation for player 2

 

Now find time

 

 

 

To find how far player 1 ran use the equation

 

So the answers are
