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.

(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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
