Asked by Jessica
ok so I have this question which asks that considering water erupts from Saturn's moon(Enceladus) and escapes into space, what would be the water's minimum speed of eruption.
A. 100km/h, B. 210km/h, C. 425km/h, D. 850km/h, E. 1700 km/h
If anyone knows how to solve this problem, please help me... it will be highly appreciated!

from wikipedia ,,,
For a spherically symmetric, massive body such as a star, or planet, the escape velocity for that body, at a given distance, is calculated by the formula
ve = √[(2 G M) / r]
G = universal gravitation constant
M = mass of Enceladus
r = radius of Enceladus
