The melting of polar ice is one effect of the greenhouse effect, or also global warming.
The greenhouse effect, as defined by Merriam-Webster, is "the <span>warming of the surface and lower atmosphere of a planet (as Earth or Venus) that is caused by conversion of solar radiation into heat in a process involving selective transmission of short wave solar radiation by the atmosphere, its absorption by the planet's surface, and reradiation as infrared which is absorbed and partly reradiated back to the surface by atmospheric gases".
In short, "</span>the warming of the surface and lower atmosphere of a planet".

Answer: ![v \approx 18.37 \frac{m}{s}](https://tex.z-dn.net/?f=v%20%5Capprox%2018.37%20%5Cfrac%7Bm%7D%7Bs%7D)
Explanation:
Let assume that system is conservative. From application of the Principle of Energy Conservation, it is noticed that initial linear kinetic energy must be equal to the gravitational energy at the top of the circle. That is to say:
![K_{1} = U_{2}\\](https://tex.z-dn.net/?f=K_%7B1%7D%20%3D%20U_%7B2%7D%5C%5C)
Where
.
![v = \sqrt{4 \cdot (9.81 \frac{m}{s^2})\cdot(8.6 m)} \\v \approx 18.37 \frac{m}{s}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B4%20%5Ccdot%20%289.81%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%29%5Ccdot%288.6%20m%29%7D%20%5C%5Cv%20%5Capprox%2018.37%20%5Cfrac%7Bm%7D%7Bs%7D)
