A Numerical Problem on conservation of momentum – An exploding shell

An 80 kg shell is flying at a speed of 36km/h. It explodes into two pieces and one piece of mass 20 kg stops. What is the velocity of other piece? (It’s a simple problem. Expect the visitors to answer soon) Incoming search terms:a 80 kg shell is flyingconservation of momentum problems shellconservation of momentum definition [...]

Collisions and Principle of Conservation of Momentum – Weblinks

According to the principle of conservation of momentum, the total momentum of a system of particles remains constant provided no external force acts on it.

Principle of conservation of momentum is one of the fundamental concepts of Physics.
