Homework Statement
A certain volcano on Earth can eject rocks vertically to a maximum height .
Part 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 m/s^2 , and you can neglect air resistance on both planets.
Homework Equations
y=yo + vo*t + 1/2 *g*t^(2)
vy=vo + g*t
The Attempt at a Solution
y=yo + vo*t - 1/2 *g*t^(2)
vy=vo + g*t
0=vo-g(mars)*t
t=vo/g
substitute this in y=yo + vo*t - 1/2 *g*t^(2)
to get y=1/2 * vo^(2)/g
After this I am stuck. The answer is 2.64H or 2.64Y
