Question

In a one dimensional collision between two identical particles A and B, B is stationary and A has momentum p before impact. During impact, B gives impulse J to A

  1. The total momentum of the ‘A plus B’ system is p before and after the impact, and (p-J) during the impact    
  2. During the impact A gives impulse J to B    
  3. The coefficient of restitution is fraction numerator 2 J over denominator p end fraction minus 1    
  4. The coefficient of restitution is fraction numerator J over denominator P end fraction plus 1    

The correct answer is: During the impact A gives impulse J to B
