1. The problem statement, all variables and given/known data[/b] Bullet B weighs 0.5 oz and blocks A and C both weigh 3 lb. The coeffient of friction between the block and the plane is [tex]\mu[/tex]k = .25. Initially the bullet is moving at v0 and blocks A and B are at rest. After the bullet passes through A it becomes embedded in block C and all three objects come to stop in the position shown. Determine the initial speed of the bullet v0. mv1 + Imp(1 [tex]\rightarrow[/tex] 2) = mv2 Imp(1 [tex]\rightarrow[/tex] 2) = int[F(t)dt] U(1 --> 2) = T2 - T1 where T is kinetic energy and U is potential energy U(1-->2) = int[F.dr] 3. The attempt at a solution I'm not really sure where to actually start with the problem besides starting from the second block. I tried using the impulse priniciple but that gives me an unknown time, force, and velocity and I'm not sure if the force would just be the fictional force. I also tried appying the work energy theorem but I'm not confident of that being useful here and it ended up giving me a huge velocity. Thanks to anybody that is willing to helps me.
