thank you very much ^^ ! you helped me so much (: !

oh may i ask a question ? . c) p1i + p2i = p1f + p2f 8kgm/s - 2kgm/s = 4kgm/s + 2kg*v2f how did you get the 4kg*m/s && 2kg*v2f ? i just want to double check aha.. ; - ; so i don't get the whole concept wrong and whatnot. and for this (Delta)p = pf - pi (Delta)p = 2kgm/s + 2kgm/s (Delta)p...

thank you very much ; - ; ... now i shall study with the answers you have provided :D !

So I'm struggling trying to grasp the concept of momentum..due to my physics teacher going WAAAAAAAY too fast && i asked for help he didn't help much at all :\..so i asked my previous physics teacher i had before transferring classes because the school " said so " but it was a bit still...

oh uh oops nvm about this question..sorry. i got help on solving this question after school with my teacher today :DD ! but thanks for the warm welcome lol.but thank you for trying to help out (: !

a 400kg cannon fires a cannon ball that exits at a speed of 20 m/s. A) what was the momentum of the cannon and ball before it was fired ? B) what is the momentum of the cannon ball alone after it was fired ? C) what is the speed of the cannon as it recoils ? Given...

YAY ! ty ty :D ! but then i have a lot more questions i have to ask about my other homework problems.. usually i stay after school to get help and understand the concepts and whatnot but i didn't have time to get to go through problems i need help with ; - ;.. sorry for the extra info that...

sorry if i might ask a lot of questions >< . I am a bit slow.. lol so if i change the final momentum to a negative i get.. final momentum = -3.85 kg*m/s but for question " E " how do i find the average force.? is it like impulse/ Δt = f i don't know if I am doing this correctly.

Momentum..initial & final & impulse. a 70g tennis ball coming towards you at 25 m/s is hit with a tennis racquet and goes away from u at 30 m/s A) what is the initial momentum of the tennis ball? B) what is the final momentum of the ball ? C) what is the change in momentum of the...
