i think the answer is 599 m/s but i’m not sure

Answer:
Explanation:
they are running directly at each other
p = m*v
where p is momentum
m is mass
and v is velocity ( physics term for speed and direction )
player A ) 80 * 8 = 640
player B ) 100 * - 5.5 = - 550
A +B = total momentum
640- 550 = 90
total mass is now player A + player B= 180
90 = 180 * v
90/ 180 = v
0.5 = v
they are moving to the right of the picture at 0.5 m/s
