Question

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

I am sure they were dazed, I have been there...
I assume they refer to Moment of force when it says momenta?
bobpursley
Momentum= mass*velocity

MassA*VElocityA+massB*VelocityB=Finalmomentum=0
so MassA*VelocityA=-MassB*VelocityB
bobpursley
Your term moment of force, is normally just called moment, it is the torque which causes rotation.
