How do you find acceleration and Fnet for a diagram containing only one object with a mass, like say 10kg, and two arrows going in the opposite directions(horizontally) with thier tips touching each side of the object. **NOTE: there are no other numbers other than the mass.

If the forces are in opposite directions, they subtract. Force is a directed number (vector) so direction matters.
