11. Problem based on law of conservation of momentum

Two hockey players of opposite teams, while trying to hit a hockey ball on the ground collide and immediately become entangled. One has a mass of 55 \(kg\) and was moving with a velocity 4.8 $m{s}^{-1}$  while the other has a mass of 55 \(kg\) and was moving faster with a velocity 5.7 $m{s}^{-1}$ towards the first player. In which direction and with what velocity will they move after they become entangled? (Enter the values up to two decimal)

 

Assume that the frictional force acting between the feet of the two players and ground is negligible.

 

Answer:  $m{s}^{-1}$
