According to the diagram which statement best describes what happens when two astronauts collide in space? Will give crown

J. Their momentum is conserved

Explanation:

According to the diagram, the best statement that describes what happens when two astronauts collides in space is that their momentum is conserved.

The momentum before collision is 320kgkm/hr and after collision it is 320kgm/s

 This collision is an inelastic collision;

    momentum before  = momentum after

              m₁v₁ + m₂v₂     =       v(m₁ + m₂)

m₁ = 80kg

v₁  = 4km/hr

m₂ = 80kg

v₂  = 0

v  = 2km/hr

 Insert the parameters;

              (80 x 4) + (80 x 0)    = 2(80 + 80)

                    320                      = 320
