# How can I find the Final velocity of the System (if perfectly inelastic) Ignoring air resistance [closed]

I am given that a bullet of mass 24.6 grams is shot at a block of 231 grams that will slide on a wooden desk with a coefficient of kinetic friction being .210. all i'm given is that the block more 32.6 meters. The problem is asking for the initial velocity of the bullet.

I know this has something to do with conservation of momentum but I can't find the Final velocity of the system especially without an applied force or some time.

• When you say 32.6 meters, is that the stopping distance of the bullet plus block after the collision? – Bob D Dec 7 '19 at 18:53
• Yes that is the stopping distance of the bullet plus the Block – Hector Espinoza Dec 7 '19 at 18:55
• Hi and welcome to physics.SE! Please note that homework-like questions and check-my-work questions are generally considered off-topic here. We intend our questions to be potentially useful to a broader set of users than just the one asking, and prefer conceptual questions over those just asking for a specific computation. – ACuriousMind Dec 7 '19 at 19:29
