The velocity of the third piece is 124.02 m/s at 1.05⁰ below the horizontal.
The velocity of the third piece is calculated from the principle of conservation of linear momentum.
mu = m₁u₁ + m₂u₂ + m₃u₃
In simple words, velocity is the speed at which something moves in a particular direction. For example, the speed of a car traveling north on a highway, or the speed a rocket travels after launching.
Linear momentum is the vector quantity and is defined as the product of the mass of an object, m, and its velocity, v. The letter 'p' is applied to express it and used as momentum for short. Please note that the body's momentum is always in the same direction as its velocity vector.
