Astronauts are testing the gravity on a new planet. A rock is dropped
between two photogates that are 1 meter apart. The first photogate
reads a velocity of 2.2 m/s and the the second photogate reads a
velocity of 7.3 m/s. What is the acceleration of gravity on this new
planet?

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

need to see circuit to get time constant

if the person is shown to have +90n, then ans is -10n.
