## 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
