I've been stuck on this test question for a while so thxs for anyinfo:
[QUOTE]
a 100. gram bullet traveling at 350 m/s strikes and sticks into astationary 5.00 kg block of wood. The combined (bullet + wood)initially slides on the horizontal frictionless surface until theyencounter a 30.0 degree inclined plane, with a coefficient ofkinetic friction between the plane and the bottom of block of .350.To what maximum height will the center of mass of the combinedblock and bullet rise above it's original vertical position?

[QUOTE]
bullet: 100g = .1 kg
wood: 5.00 kg
[/QUOTE]

I used this formula:
[QUOTE]
Vf(B+W) =[(m1-m2)(/m1+m2)](V10)+[(2m2)/(m1+m2)](V10)
[/QUOTE]

I believe that you use C.O.M.E. or C.O.K.E. not sure any inputwould be helpful.
