Two boxes are at rest on a smooth, horizontal surface. the boxes are in contact with one another. if box 1 is pushed with a force of magnitude f = 12.2 n , the contact force between the boxes is 8.90 n ; if, instead, box 2 is pushed with the force f, the contact force is 3.30 n . in either case, the boxes move together with an acceleration of 1.50 m/s2. what is the mass of box 1? what is the mass of box 2?

mass of box 1 = 2.20 kg

mass of box 2 = 5.93 kg

Explanation:

Let the mass of box 1 and box 2 is respectively

and

so we will have

Force applied on box 1 then acceleration

Now we know that contact force between them in above case is given as

now we have

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
