A 3.2 kg box hangs on a rope without mass and that does not stretch, the rope hangs on another 3.2 box that is tied with another rope (also without mass and that does not stretch) as shown in the figure. (a) If the boxes are at rest, what is the tension in each string? Upper rope __, lower rope __. (b) If the boxes are pulled upwards with an acceleration of 1.60 m / s ^ 2, calculate again the tension in each rope. Upper rope ___, lower rope ___. Use a coordinate system with positive Y up, and positive X to the right.
please answer all of them, i am having trouble uploading the images and i dont have questions left to trie.
