Are the following and isolated collisions possible? Explain why or why not
A. Object A, initially travelling to the right, collides with object B that is at rest. After the collision, object A moves back to the left and object B remains at rest.
B. Object A, initially travelling to the right, collides with object B that is at rest. Object B is more massive than object A. After the collision, object A moves back to the left and object B moves to the right.
C. An object is travelling to the right and collides with another object that is at rest. After the collision, both object travel to the right, but at different speeds

Answer:
Part A: Possible: This is elastic collision. in this condition body A is lighter than body B. m1<<<m2. so when m1 elastically collide with m2, after collision come with the same speed and m2 remain at rest.
Part B : not possible
according to given condition m2>>>>m1 so it is not possible to move massive object by a lighter object.
Part C: possible
it is elastic collision, in this condition m1>>m2 so after collision m1 move to right with double velocity of m2 and m2 move to right with same speed.
