Answer:
Displacement from the starting position is 103.21m
Explanation:
If you draw these directions, it will create the two legs of a triangle.
Using this method, you can visualize why your displacement is what it is.
Using the pythagorean theorem
Plug in both values
c = 103.2085
c= 103.21
Theoretically, if the objects have the same mass and are moving towards each other at a speed of 
, after a perfectly elastic collision, the object A is supposed to move with the same velocity in the opposite direction.
