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.

A box of mass m = 10.0 kg is attached to a rope. The other end of the rope is wrapped around a pulley with a radius of 15.0 cm. When you release the box, it begins to fall and the rope around the pulley begins to unwind, causing the pulley to rotate. As the box falls, the rope does not slip as it unwinds from the pulley. If the box is traveling at a speed of 2.50 m/s after...

A rope of negligible mass hangs vertically on each side of a pulley. The pulley, which has mass 1.00 kg and radius 20 cm, can be modeled as a thin uniform cylinder. One end of the rope is tied to a box of mass 10.00 kg; this box is resting on the ground. The other end of the rope dangles freely. Then a 15.00 kg monkey, who is initially standing on a ledge 2.00 m above the floor, grabs the...
