Acceleration Due to Gravity Problem HELP

AI Thread Summary
To calculate the acceleration due to gravity on Titania, the correct formula is g = GMe/Re^2, where Me is the mass of Titania and Re is its radius. Titania has 1/8 the radius and 1/1700 the mass of Earth, which significantly affects the calculation. Users in the discussion confirm that the equation is appropriate for this problem, despite initial confusion about the results. It's important to ensure all values are correctly substituted into the formula. The conversation emphasizes the necessity of double-checking calculations to arrive at the correct answer.

Acceleration Due to Gravity Problem **HELP**

Homework Statement


Titania, the largest moon of the planet Uranus, has 1/8 the radius of the Earth and 1/1700 the mass of the earth...

What is the acceleration due to gravity at the surface of Titania? (m/s^2)


Homework Equations


g= GMe/Re^2

(Me) mass of planet
(Re) radius of planet


The Attempt at a Solution



well, i thought this was the right way of doing the problem, but i get a totally wrong answer and i am totally confussed on if this is the right equation for this problem or not.

You left this part out.
 
ok i fixed it
 
please show what you tried [even if it is wrong]
 
This is definitely the right equation.

Thread 'Errors and significant figures'

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'

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...
