Predict/Calculate Volcanoes on lo Astronomers have discovered
several volcanoes on Io, a moon of Jupiter. One of them, named
Loki, ejects lava to a maximum height of $2.00 \times 10^{5} \mathrm{m}$ . (a) What is the initial speed of the lava? (The acceleration of gravity on lo is
1.80 $\mathrm{m} / \mathrm{s}^{2} . )$ (b) If this volcano were on Earth, would the maximum height of the ejected lava be greater than, less than, or the same as
on lo? Explain.
