how do you if the collision is in 2 dimensions?
Yes. Apply momentum conservation. That's all you need. You have the initial total momentum; and you have the final momentum of one piece. Remember that momentum is a vector, so direction is important.momentum is conserved
OKSo inititial momentum of the capsule+ im of the projectile= fm of capsule+fm of projectile
No. Initially the projectile was part of the capsule, so treat them as one piece at that point.im of projectile is 0
I suggest that you call the initial direction of the capsule to be in the +x direction. And call the direction of the projectile to be the -y direction. (Draw yourself a picture.)then we find an equation for final v of the casule
so now we apply this to the x direction right?
Remember to treat momentum as a vector. First find the x and y components of the initial momentum of capsule + projectile:ok so that means, the initial momentu of the capsule includes the projectile as well,
So it will be 3000v= 25*v of projectile+3000*Vf of capsule
Now we isolate Vf.
Vf= (3000v-25*V of projectile)/3000
k so i tried to draw the diagram, but i still dont understand
