Answer:
Perfectly inelastic collision 
Explanation:
There are two types of collision. 
1. Elastic collision : When the momentum of the system and the kinetic energy of the system is conserved, the collision is said to be elastic. For example, the collision of two atoms or molecules are considered to be elastic collision. 
2. Inelastic collision: When the momentum  the system is conserved but the kinetic energy is not conserved, the collision is said to be inelastic. For example, collision of a ball with the mud. 
For a perfectly elastic collision, the two bodies stick together after collision. 
Here, the meteorite collide with the Mars and buried inside it, the collision is said to be perfectly inelastic. here the kinetic energy of a body lost completely during the collision. 
 
        
             
        
        
        
Answer:

Explanation:
From the question we are told that:
Bowling ball Speed 
Beach ball Speed 
Let The Mass be equal i.e 
  
Therefore
Generally the equation for Velocity of beach ball after collision 
 is mathematically given by
Since Velocity is Vector Quantity 
Therefore
