I write on paper. I find it much faster.

5 litres. I did check my work. I don't understand the question. If I could figure out how to fix it I wouldn't be asking for help.

There are 1000L in 1 cubic metre. So the volume is .5 litres?

Sorry for double posting, but: The weight of a floating object is equal to the amount of fluid displaced. Therefore, since the object weighs 5kg, 5kg of water is displaced. density=mass/volume volume=mass/density volume=5kg/(1000kg/m3) volume=0.0005m3 The 5kg of water has a volume of...

So 5kg of water is displaced... Do I find the volume of 5kg of water and does that also equal the volume of the object?

That the water weighs more? Or the object is less dense?

Homework Statement If a 5kg object floats in water (density=1000 kg/m3) with 20% of it's volume above the surface of the water, what is the volume of the object? Homework Equations Archimedes' Principle = the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or...

I eventually solved it using the first method I tried (breaking into x and y components. Thanks for your help.

Tried it this way, still not getting correct answer

38.3 degrees

This is messy, sorry, but I'm at this point in trying to figure the question out!

I'm not sure, are they supposed to be the same? They add up to 180 degrees.

I've tried this a few time and I haven't been able to get the correct answer :( Do you spot a mistake I could have made? If you can't read my writing I can type it out!

Homework Statement Homework Equations ΣM=Στ The Attempt at a Solution I know how to get the net torque about point P, but I am having difficulty determining where the moment arms for each force should be. I did 9 simpler questions before this no problem, but this diagram is a bit more...

I didn't notice the change in wording, thanks for pointing it out!
