Two dogs, one 20kg and one 50kg, pull on a bone. They each pull with the same force, but in opposite directions. What will happen next?

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

vapour or gas assuming atmospheriv pressure

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
