The acceleration of the object can be calculated as follows:
F= 35 N = ma = 2a
a = 17.5 m/s^2
Normal force is the component, perpendicular to the surface of contact, of the contact force exerted on an object by, for example, the surface of a floor or wall, preventing the object from falling. It is calculated as:
Normal force = mg = 2 x (9.8) = 19.6 N
