Two football players collide head-on in midair while chasing a pass. The first player has a 92.5 kg mass and an initial velocity of 5.50 m/s, while the second player has a 116 kg mass and initial velocity of -6 m/s. What is their velocity (in m/s) just after impact if they cling together? (Indicate the direction with the sign of your answer.)

Their velocity (in m/s) just after impact if they cling together is -0.9 m/s.

Final speed of the two players

Apply the principle of conservation of linear momentum;

Pi = Pf

where;

  • Pi is initial momentum of the players
  • Pf is final momentum of the players

(92.5)(5.5)  +  (116)(-6)  =  v(92.5 + 116)

508.75 - 696 = v(208.5)

-187.25 = 208.5v

v = -187.25/208.5

v = -0.9 m/s

Thus, their velocity (in m/s) just after impact if they cling together is -0.9 m/s.
