(a) If the boxes are at rest, what is the tension ineach string? Upper rope __, lower rope __. (b) If the boxes arepulled upwards with an acceleration of 1.60 m / s ^ 2, calculateagain the tension in each rope. Upper rope ___, lower rope ___. Usea coordinate system with positive Y up, and positive X to theright.
please answer all of them, i am having trouble uploading theimages and i dont have questions left to trie.
