Newton’s second law establishes the relationship between mass, net applied force, and acceleration given by f=ma. consider a 4 kg box of holiday candy on a horizontal surface such as a table. there is a 10n applied force to the right and a 2n force to the left. the box accelerates with a magnitude of

a= 2 m/s^2

Explanation:

take to the right as positive

let Ftot be the total forces acting on the box , m be the mass of the box and a be the acceleration of the box.

Ftot = 10 - 2 = 8 N

and,

Ftot = ma

   a = Ftot/m

      = 8/4

      = 2 m/s^2

therefore, the acceleration of the box is of magnitude of 2 m/s^2.

whichever one it is, it's definitely not one that you included on the list you provided.

i don't know that i agree with that but what's the question ?
