During a soccer game two players come from the opposite directions and collide when trying to head the ball. They come to rest in midair and fall to the ground. Describe their initial moments?

Dazed? Confused?

I suspect you want initial momentums. They were equal and opposite directions.

• Physics -

Ha Ha sorry, momenta.... My typo...

I am sure they were dazed, I have been there...

• Physics -

I assume they refer to Moment of force when it says momenta?

• Physics -

Momentum= mass*velocity

MassA*VElocityA+massB*VelocityB=Finalmomentum=0
so MassA*VelocityA=-MassB*VelocityB

• Physics -

Your term moment of force, is normally just called moment, it is the torque which causes rotation.
