!HELP!

The Singapore Flyer, until recently the world's largest Ferris wheel, completes one rotation every 32 minutes.1 Measuring 150 m in diameter, the Flyer is set atop a terminal building, with a total height of 165 m from the ground to the top of the wheel. When viewed from Marina Centre, it turns in the clockwise direction. State the o'clock position on the wheel and height above the ground of a person who has ridden the wheel for 24 minutes. Assume that the person boarded the wheel at the 6 o'clock position.i don't know how to do this problem.please help!and thanks in advance.

Hi mak23! Welcome to MHB! ;)

Let's see... it starts at the bottom position (6 o'clock), and makes a full turn in 32 minutes.
That means it's at the top after 16 minutes isn't it?
And that's at 165 m from the ground.
How high would it be anyway at the starting position?
We should be able to tell, shouldn't we? Since it's given that the wheel is 150 m in diameter.

It also means that after 8 minutes, it's at a quarter of its turn.
And at 24 minutes, it's at three quarters of its turn, which is what the problem is about.
Can we tell how high that would be?
 
Thank you for the help!

I understand now.

so after 24 minutes the person should be at the 3'o clock position. And the person would be at a height of 75 m.

ahaa... since its on a building of 165 m, the person would be 165-75=90 m.Right?
 
Yep. (Nod)
 

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...

Thread 'Useless continued fraction for 1'

I'm interested to know whether the equation $$1 = 2 - \frac{1}{2 - \frac{1}{2 - \cdots}}$$ is true or not. It can be shown easily that if the continued fraction converges, it cannot converge to anything else than 1. It seems that if the continued fraction converges, the convergence is very slow. The apparent slowness of the convergence makes it difficult to estimate the presence of true convergence numerically. At the moment I don't know whether this converges or not.
