Hello, I wanted to know if anyone had a possible solution to the question which is how much time it would take to hit Earth. I've been trying to figure it out but can't figure out how to fit time into the overall equation because I always just get the equations in terms of radius.
I was thinking about this question:
So if a rock fell 20,000 meters to Earth assuming no air resistance and no other gravitational forces from anything but Earth, how long would it take the rock to hit Earth? Keep in mind acceleration is changing through the gravity equation as the rock gets...
