If the Day recorded in 2 is 14 then (poorly worded problem) I will assume the mass is 14 Kg. To find the weight, we use F = ma where a = g = 9.8 m/s2 and the force is the weight W, so in other words W = mg.
That means W = (14 kg)(9.8 m/s2) = 137.2 Newtons. Since there are 2 significant figures in both the mass and the value of g, it is appropriate to round the answer to 2 sig figs so W = 140 N.
An example of physical force is when the priests lifted the ark of the covenant (Joshua 3:6: And Joshua spake unto the priests, saying, take up the ark of the covenant, and pass over before the people. And they took up the ark of the covenant, and went before the people.).
The Ark had a mass and so an associated weight. The priests lifted the Ark so they used a total physical force equal to its weight to lift it. Verse 12 discusses 12 priests so each priest would have lifted 1/12 of the weight of the ark.
