Answer: A certain volcano on earth can eject rocks
Chapter 2, Problem 2.71(choose chapter or problem)
A certain volcano on earth can eject rocks vertically to a maximum height H. (a) How high (in terms of H) would these rocks go if a volcano on Mars ejected them with the same initial velocity? The acceleration due to gravity on Mars is \(3.71 \mathrm{\ m} / \mathrm{s}^{2}\) ; ignore air resistance on both planets. (b) If the rocks are in the air for a time T on earth, for how long (in terms of T) would they be in the air on Mars?
