    Ocean Volume
AI Thread Summary
To find the volume of the object thrown into the ocean, use the formula for volume based on mass and density, which results in a volume of approximately 1.74 m³. According to Archimedes' principle, the volume of water displaced by the object is equal to the volume of the object itself. The object will float if its density is less than that of seawater, which it is not in this case, as its density is 681.0 kg/m³ compared to seawater's 1024 kg/m³. Therefore, the volume that sticks out of the water can be calculated by determining the buoyant force and the submerged volume. The discussion emphasizes the importance of showing calculations and understanding the principles involved in solving such problems.

An object with a density of 681.0 kg/m3 and a mass of 1183.0 kg is thrown into the ocean. Find the volume that sticks out of the water. (use pseawater = 1024 kg/m3)

You can't just "throw" the problem in this "ocean" and expect a solution. You need to give your thoughts, show your working.

Use Archimedes' principle.
 
Nice answer!

1. What is the volume of this object?


2. What is the volume of water it displaces?
(Again: "Archimedes' principal".)

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
