(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Gravity varies in two different places by 0.01 m/s^2. The jumper has a mass of 72 kg. What is the difference in jump height in each location? I have a couple of height measurements, but I'm pretty sure they are irrelevant because I am looking for a difference (and the problem says the difference in the heights listed is not due to gravity).

2. Relevant equations

I tried using F(jump)-F(weight) = ma, where a = 2h/t^2 and F(weight) = mg.

I also tried using delta x = 0.5g*t^2

3. The attempt at a solution

For both equations, I enter in the different gravities into two equations and subtract the two equations. I used 9.8 and 9.81, though I suppose I could use any two numbers varying by 0.01.

In both attempts, I come up with a difference of 0.005, but the answer checker tells me that I am wrong.
