Question: In physics , the escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a massive body.

Inphysics, theescape velocityis the minimum speed needed for an object to "break free" from the gravitational attraction of a massive body. The escape velocity from earth is about 40,270 km/h (25,020 mph). For a massive celestial object (e.g., a star or planet), the escape velocity at a given distance is given by the formula:
ve=2GMr
where ve is the escape velocity in meters per second, G is the universal gravitational constant and is equal to 6.67x10-11 m3/kg/s2, M is the mass of the object in kilograms, and r is radius of the object in meters.
QUESTION: Enceladus has a mass of 1.08x1020 kg and a radius of 2.521x105 meters. What is the minimum speed (in meters per second) that the plumes must travel to escape the gravity of Enceladus? Round to the nearest whole number.
