Conservation

A block of mass m1 = 2.0 kg slides from height 5.0 meters on a frictionless surface and collides elastically with a block of mass m2 = 4.0 kg . 

 

Show complete solution step by step.

What is the maximum height to which m1 rises after the collision?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Conservation of momentum: total Initial momentum of the system = total final momentum of the system Pi =Pf                  P = mv

Conservation of mechanical energy  Ei = Ef              E= U + K         U= mg H     K=1/2 mv2

For elastic Collison   :   V1f = ( m1  - m2 ) V1i/ ( m1 + m2 )       V2f = ( 2m1  ) V1i/ ( m1 + m2)
