Two football players collide and stick together what type of motion is it? Help me please!!

My , oh my , what a pervy question.

Two players collide with each other (I dont think they stick together though) and what happens during collision of two bodies is that after the collision , they get pushed apart due to the momentum generated (Newton 2nd law) during collision because they collide with such heavy forces.

Also this is Linear motion (straight line motion).  

The collision is inelastic collision because both players hit each other (stick?) with different velocities.

Linear motion and Inelastic collision.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

mistakes are ok
