Question

You are exploring a planet and drop a small rock from the edge of a cliff. In coordinates where the +y direction is downward and neglecting air resistance, the vertical displacement of an object released from rest is given by
y ? y0 = 1/2 gplanet
where gplanet is the acceleration due to gravity on the planet. You measure t in seconds for several values of
y ? y0
in meters and plot your data with t2 on the vertical axis and
y ? y0
on the horizontal axis. Your data is fit closely by a straight line that has slope 0.700 s2/m. Based on your data, what is the value of gplanet?

Not sure how to solve, sorry about the format!

Explanation / Answer

You are simply measuring d and t for an object falling from rest.

Fitting the data to the equation d =
