F=ma is the net force on the object. That is standard newtons law.

N here isnt for the static case, N is the normal force, meaning the total force from the surface to the mass. F=mv, ja72's law? LOL. F=mdv/dt

Can you clarify what you are looking for? The force from the surface to the ball? Is that what? Please ask your question, you told a story, it was really annoying to have to guess your question.

I downvoted your answer for beeing needlessly complicated and hiding all the simple concepts needed. Also you post it when there is already a simple and correct answer, and you didnt upvote it.
