The second player is 91 meters far from the first player.
Why?
First, let be the +y the North, so, to solve the problem we can use the following formula:
[tex]y=yo+v_o*t+\frac{1}{2}*a*t[/tex]
Now, subsituting the given information, we have(assuming that the speed is constant):
\\\\y-yo=13\frac{m}{s}*7s+\frac{1}{2}*0*7s\\\\y-yo=91m\\\\distance=91m[/tex]
Hence, we have that the second player is 91m far from the first player.
Have a nice day!
