this is really late but i need the little bit of credit this will give me to help my grade a little bit. i got a D on my last exam so I need all the help i can get. I really forget what we learned during this time period but im guessing it had to do with momentum. Momentum is conserved and never can be be destroyed. Momentum in equals momentum out. so like for a grenade momentum is zero at the beginning and if you add up the shrapnel after the explosion it will equal to zero again. This is a picture of killahs. we are like grenades cause we explode. haha or something like that
