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.
