    Newtons Weight
AI Thread Summary
The giant squid, the heaviest invertebrate, weighs approximately 1.5 tons, equivalent to about 1,016.05 kilograms. To convert this weight to Newtons, one must multiply the mass in kilograms by the acceleration due to gravity, which is 9.8 m/s². A participant attempted this conversion but initially used an incorrect value for the ton-to-kilogram conversion. The correct conversion should yield a weight of approximately 14,880 Newtons. Ensuring proper unit conversions and calculations is essential for accurate results.

The heaviest invertebrate is the giant squid, which can have a weight of about 1.5 (imperial) tons spread out over its length of 64 feet. What is its weight in Newtons?

I tried converting the tons to kilograms and multiplying by 9.8 but didn't get the right answer. Where should the 64 feet be used?

How did you convert tons to kilograms? If you look online, an imperial ton is equivalent to 1016.04691 kg. So, you did have the right idea in going about the problem, but just use this number instead and it should work.
 
There must be something else. I tried your plan and got 14935.88 which I'm told is still wrong. Thanks anyway.
 
A Newton is (kg*m)/s^2, so convert your length and see if your answer is correct.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging 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...
