Completely Inelastic Collision
Shows two bodies before and after they have a completely inelastic collision (meaning they stick together). The body with mass happens to be initially at rest. We can refer to that body as the target, and the incoming body as the projectile. After the collision, the stuck-together bodies move with velocity V. For this situation.
If we know values for, say the masses and the initial velocity Vii of the projectile, we can find the final velocity V with. Note that V must be less than Vii_ because the mass ratio m must be less than unity.
