Q. The first active volcano observed outside the Earth was discovered in 1979 on Io, one of the moons of Jupiter. Assume a volcano on another moon is observed to be ejecting material to a height of about 2.19 x10^5 m. Given that the acceleration of gravity on this moon is 1.89 m/s2. Find out the initial velocity of the ejected material.
