Question

Example 9.8 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 60 kg and was moving
with a velocity 5.0 m s' while the other
has a mass of 55 kg and was moving
faster with a velocity 6.0 m s' towards
the first player. In which direction and
with what velocity will they move after
they become entangled? Assume that
the frictional force acting between the
feet of the two players and ground is
negligible.​
