I don't understand how to get the force that the table is exerting on the box..

I'm just confusing myself on the equation and everything..

but what would the 'ground' be because there is nothing pushing it or anything?

so then what equation does that go into for net force? because then I have to do what the table exerts on to each box.

but then what equaton would I use if F=0? because then wouldn't it not work out correctly?

but then what equation would I use for that if F=0? because then it wouldn't come out right?

If there was no box, the weight would move until it hit the ground. And if there was only a box, it would be resting on the table and wouldn't be moving anywhere.

I don't get what difference it makes at all. I'm so confused on how to do this one.

I'm not doing it together. I put it up now so I wouldn't forget about it?

I don't know how to show the diagram on here, otherwise I would. On the box..wouldn't normal force and tension being going upwards, gravity going downwards? And the mass would have gravity and acceleration going down? I'm not really sure about the difference it makes.

Homework Statement One 3.5 kg paint bucket is hanging by a massless cord from another 3.5 kg paint bucket, also hanging by a massless cord. (a) If the buckets are at rest, what is the tension in each cord? (lower cord) (upper cord) (b) If the two buckets are pulled upward...

okay, then there is no friction, but I drew the diagram but I still am confused about how to figure the problem out and plugging things in where.

We just have to assume about the friction being there, but what do you mean by just the sum of all of the forces? And normal force, tension, friction, acceleration, velocity, and acceleration are all acting on the box.

Okay...I'll post it in the homework one next time. I'm sorry about that.. And I've tried multiplying all of them by gravity and it's gotten me no where and I don't know what else to do for it.

A box weighing 71 N rests on a table. A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end Determine the force that the table exerts on the box if the weight hanging on the other side of the pulley weighs each of the following. (a) 27 N...
