Here's the question: Two boxes are placed on top of one another. The top box has a weight of 20 N and the bottom box has a weight of 50 N. You can neglect friction between the bottom box and the floor, but uS = 0.5 and uK = 0.4. You can assume g = 10m/s^2. Both boxes are initially at rest...

Oh, sorry. I'm in a rush and I actually didn't read it. I attempted to make a freebody diagram, but all I came up with was that the two tensions added up equaled to the force of gravity. I don't think that is right though. I feel like there is supposed to be some sort of centripetal force...

Homework Statement Two wires are tied to the 150 g ball shown in the figure. The ball revolves in a horizontal circle at a constant speed of 5.0m/s. gravity is 10m/s2. Draw a free-body diagram and specify any relevant dimensions or angles. Write expressions applying Newton's second...
