No, 3 is the case.
Consider momentum of the ball is a vector, in one direction going, and one direction coming. The difference of momentum is twice the original momentum
mv-(-mv)=2mv
Can someone please help me with the following 2 questions? I wasn't sure if I was grasping the whole idea.
**Consider a baseball that is caught and then thrown at the same speed. Which case illustrates the greatest change in momentum, which requires the greatest impulse: the baseball (1) being caught, (2) being thrown or (3) being caught and then thrown back?**
**I think case (2) illustrates the greatest change in momentum.
**I think case (3) requires the greatest change in impulse.
THANX SO MUCH FOR THE HELP!!
