    Thanks everyone for all your help. I really understand the ones that you helped me to work out! Thanks again!

    A small bomb, of mass 12 Kg, is moving toward the North with a velocity of 5.0 m/s. It explodes into three segments: a 6.0 Kg fragment moving west with a speed of 9.0 m/s; a 4.0 Kg fragment moving East with a speed of 10 m/s; and a third fragment with a mass of 1.0 Kg. What is the velocity of...

    how did you get 3.68m/s?

    Please Help with Physics!

    i now got l2.35l m/s (abs value)
  5. S

    Please Help with Physics!

    should i convert that to 0.1542m/s? 9m (m)(-9.8)(.4873)+1/2(m)(v)2=1/2(m)(v)2

    that would be cm/s

    just seemd kinda large, doesn't it?

    i got an ending velocity of 15.42 m/s

    yeah, i got 48.73 cm which converts about the same but now i have: mgh+1/2 mv2=1/2 mv2 how will the masses cancel?

    so now that i have the angle, i can set TEa=TEb. Does it start with PE and KE? so that.... TEa=PE+KE and TEb=KE ?

    yeah, SOH CAH TOA, right? but i don't even have an angle

    yeah i see that the masses will cancel out....but there is one problem....i've never had trig and don't know where to begin with a trig formula...is there a name?

    Well, i figured the first one out. I found the velocity of mass B prime and used it to find the velocity of mass A prime. I'm working on number 4 right now. I'm thinkin that total energy at point A is equal to total energy at point B but there is no mass or angle and I don't know how to...

    Well, i do know that there is an elastic head-on collision which means change in momentum and conservation of KE.
