Calculating the Average Force on a Meteor Upon Entering Jupiter's Atmosphere

Click For Summary
A meteor with a mass of 1 kg enters Jupiter's atmosphere at a speed of 20 km/s and penetrates 100 km before disintegrating. The average force acting on the meteor is calculated using the work-energy principle, leading to a correct answer of 200,000 N, despite initial confusion regarding the calculations. Participants in the discussion clarify that the average force can be determined using the formula for kinetic energy and work, emphasizing that kinematic equations are not applicable due to non-constant acceleration. The conversion from kilometers to meters is also corrected, reinforcing the importance of accurate unit conversion in physics problems. Overall, the discussion highlights the need for a proper understanding of average force and the appropriate methods to calculate it in varying conditions.

Unless the force/time aspect is controlled by an observer (a person), t should be able to be factored out algebraically
Not sure what you are saying. Are you maintaining that there's no difference between the time-averaged force and the distance-averaged force?
