Terminal velocity of 20 lb bowling ball at 40,000 feet

Click For Summary

Discussion Overview

The discussion revolves around estimating the terminal velocity of a 20 lb bowling ball falling from a height of 40,000 feet. Participants explore the relevant equations and considerations, particularly focusing on the drag coefficient and the implications of such a fall.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant seeks assistance in estimating terminal velocity, specifically questioning the appropriate drag coefficient to use.
  • Another participant provides a link to a resource on drag coefficients, suggesting it may contain useful information.
  • There is a humorous exchange regarding the feasibility of aiming a bowling ball from such a height, with some participants joking about the use of laser or GPS guidance systems for the bowling ball.
  • Participants express skepticism about the practicality of aiming a bowling ball from 40,000 feet, with one suggesting that the design of the bowling ball could include correction thrusters.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the practical aspects of the scenario, with humor and skepticism about the feasibility of aiming a bowling ball from such a height dominating the discussion.

Contextual Notes

The discussion includes assumptions about the drag coefficient and the nature of the fall, which remain unresolved. The humorous elements may distract from the technical inquiry regarding terminal velocity.

I am looking for an estimated terminal velocity of a 20 lb bowling ball falling through 40,000 feet. I have looked at the equation, but am not sure what to use for the drag coefficient. Thanks for any help.

Um, why do you ask?

I just did some calculations and i sincerely hope he isn't thinking what i think you were thinking when you asked this... :biggrin:
 
everyone needs to calm down, there is no way to aim a ball from 40,000 feet

What if it's a laser-guided bowling ball.

Exactly! Those 3 little holes can be used for more than just 2 fingers and a thumb :bugeye:
 
No, it's a GPS guided bowling ball. Those 3 holes are correction thrusters.
Jeeze, do I have to teach you guys EVERYTHING?
