**Inelastic Collision Formula**

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**.

**Inelastic Collision Formula** is articulated as

Where,

mass of body 1 = m_{1}

mass of body 2 = m_{2}

Initial velocity of body 1 = u_{1}

Initial velocity of body 2 = u_{2}

Final velocity of both the bodies = v

The final velocity for Inelastic collision is articulated as

Inelastic collision formula is made use of to find the velocity and mass related to the inelastic collision.

**Inelastic Collision – Solved Examples**

Underneath are some questions based on inelastic collision which may be helpful for you.

**Problem 1: **The bullet of mass 0.02 Kg is fired from a gun of mass 5 Kg recoils with the speed of 8 ms^{-1}. Compute the Velocity after the collision?

**Answer:**

Known:

m (Mass of bullet)= 0.020 Kg,

M (Mass of gun) = 5 Kg

Let v be the final velocity, to calculate it we use the formula

M(0.08) = m(v)

**Problem 2: **Compute the final velocity if an object of mass 2 Kg with initial velocity 3 ms^{-1} hits an other object of mass 3 Kg at rest? (Collision is inelastic)

**Answer:**

Known:

m_{1} (Mass)= 2 Kg,

m_{2}(Mass) = 3 Kg

u_{1 }(Initial Velocity of first mass)= 3 ms^{-1},

u_{2} (Initial velocity of second mass) = 0
