   Hi I wonder if anyone can help, im stuck on this question.
   
   1.Two smooth spheres A and B, of masses of 300g and 700g respectively, are travelling towards each other along the same horizontal line with speeds of 8m/s and 4m/s respectively. After the collision, the direction of motion B has been reversed and its travelling at a speed of 2m/s
   
   Find:
   a)The final speed of A after the collision
   bThe total loss in kinetic energy due to the collision.
   
   
   Any help would be greatly appreciated.

   What's conserved during the collision?
