Question: Suppose you are an astronaut and you have been stationed on a distant planet. You would like to find the acceleration due to the gravitational force on this planet so you devise an experiment. You throw a rock up in the air with an initial velocity of 12 m/s and use a stopwatch to record the time it takes to hit the ground. If it takes 7.4 s for the rock to return to the same location from which it was released,
Part A: What is the acceleration due to gravity on the planet?
I need help to find the acceleration due to gravity on the planet.
