The crash in which kinetic energy of the system is not conserved but the momentum is conserved, then that collision is termed as Inelastic Collision.
Formula of Inelastic Collision
The inelastic collision formula is articulated as
Where
mass of body 1 = m1
mass of body 2 = m2
The initial velocity of body 1 = u1
The initial velocity of body 2 = u2
The final velocity of both the bodies = v
The final velocity for Inelastic collision is articulated as
