A 21.6kg box rests on a table. A 19.3kg box is placed on top of the first box, as shown. Determine the total force in N that the boxes exert on the table.
FIND f=ma for both and add them up?
a=9.8 gravity rite?

MathMate,
The force exerted on the table is the total of the masses in kg multiplied by g=9.8 m/s². The result is in N.
