Answer:
no force is required.
as zero acceleration is there.
FORCE IS USED TO MAKE CHANGE...here we have to keep it in the same STATE (not solid, liq, etc.. state of motion,rest,etc I meant) and there is no opposing force also so the object will just stay in its state of motion with v=12m/s
✨Well there are many other opposing factors we can consider in real life situation but the above is the answer to your question... I m sure about it..✨
