Question

two football players are running toward each other. One football player has a mass of 105 kg and is running at 8.6 m/s. The other player has a mass of 90kg and is running at -9.0 m/s. The momentum of the system after the football players collide is___ kg*m/s.?

Answer 1

p=mv

 

p₁=(105kg)(8.6m/s)= _____ kgm/s to the right.

p₂= (90kg)(-9.0m/s)=______kgm/s (Remember your negatives.  negative means to the left, and straight at player 1)

 

Each momentum value is a VECTOR.  To find the total momentum left in the system after collision, you must add your vectors.  This means p₁+p₂= Σp.  Remember your negatives when adding vectors.
