If a body is in freefall and has reached its terminal velocity say 56 metres/s, its acceleration is zero, how do you work out with what force it would hit the ground
The discussion revolves around calculating the force with which a body in freefall would hit the ground after reaching terminal velocity. Participants explore various approaches to determine this force, considering factors such as mass, impact time, and distance of impact.
Participants do not reach a consensus on the correct method for calculating the force of impact, with multiple competing views and corrections being presented throughout the discussion.
Some responses indicate a reliance on specific assumptions, such as the final velocity being zero and the nature of the landing area, which may affect the calculations. There is also mention of potential confusion between different physical concepts.
Should be just mass of falling object times speed with which it impacts. You should probably, for the sake of simplicity, assume that the landing area has no elastic properties. The force would be the same even if the thing lands in a bowl of Jell-O, but it would be distributed a lot differently.sweenep said:If a body is in freefall and has reached its terminal velocity say 56 metres/s, its acceleration is zero, how do you work out with what force it would hit the ground
Shhh! It happens.nishant said:oh!I made a mistake
I cannot believe that I confused 'force' and 'energy'.Chi Meson said:Beg your pardon, but the last two responses are incorrect.
Sorry, guys. The terms just kind of swapped places in my head and I didn't notice. It's like when I'm stuck on a crossword puzzle answer for hours, then suddenly realize that I've misread the clue eight times in a row. (In my defense, I was on my 7th beer at the time.)
