The problem involves calculating how far the Earth moves when a person jumps off a table, specifically focusing on the interaction between the person's mass and the Earth's mass during the fall.
The discussion has progressed with participants sharing their calculations and reasoning. Some have provided guidance on how to approach finding the distance the Earth moves during the fall, while others are still exploring the necessary steps to arrive at a solution.
Participants are working under the constraints of the problem statement, including the height of the table and the mass of the jumper. There is an ongoing exploration of the time it takes to fall and the corresponding movement of the Earth.
If 666.4 N is the force that the Earth exerts on you, what the force that you exert on the Earth?Paymemoney said:ok, i had another try of this question and i went W=mg which is 68 * 9.8 i get the force 666.4N then what should i do next?
Paymemoney said:the same because of Newton's Third Law, so i found the acceleration by doing the following:
Mass of Earth is 5.97 * 10^24 (according to the book)
637 = (5.97 *10^24)a
a=1.06*10^-22 m/s^2
now how do i find how far toward me does Earth move during the time i fall?
