Use the illustration showing a collision between two metal ball bearings to answer the questions below.  You will need to use the conservation of momentum to help you with the calculation problems.  m₁v₁ = m₂v₂   and    P = mv (momentum equals mass times velocity)

1.  Calculating:  Using the formula for momentum to find the momentum of each ball before and after the collision.  Assume the mass of each ball is 0.4kg.
 
 
 
 
 
 
 

2.  Inferring: Find the total momentum before and after the collision.  Is the law of conservation momentum satisfied in this collision?  Explain.
