no edit summary
: During elastic collisions [[Kinetic Energy Store|kinetic energy]] is conserved, so the total [[Kinetic Energy Store|kinetic energy]] before the collision is equal to the total [[Kinetic Energy Store|kinetic energy]] after the collision.
: During elastic collisions the [[object]]s bounce off one another.
 
<math>p_{before} = p_{after}</math>
 
Since:
 
<math>p = mv</math>
 
Then:
 
<math>m_1 v_1 + m_2 v_2</math>
 
Where:
 
<math>m_1</math> = The [[mass]] of [[object]] 1.
 
<math>v_1</math> = The [[velocity]] of [[object]] 1 after the explosion.
 
<math>m_2</math> = The [[mass]] of [[object]] 2.
 
<math>v_2</math> = The [[velocity]] of [[object]] 2 after the explosion.
