5 meters?
Like less than 1 second |
|
|
Like 1.5 seconds or around there. Only 15ft. |

Actual answer...
Since an object with no interference falls at 9.8 m/s squared, a person falling from the velocity of 5 meters to 0 meters sets up this problem.
9.8 m/s(2) = Vf - Vi / t
9.8 m/s(2) = 5/t
Since it is common sense that it takes 1 second to fall 9.8 meters, it will take less than one second, so you take 5 and divide it by 9.8, getting you the nice answer of....
0.510204082 seconds
Thanks for participating! |

u cant calculate tht without finding out the initial weight of the person |

or without claaulating how tall the bilding is in american units |

@ iSS
But if an object falls at 9.8 per second, and this person is falling 5 meters, 9.8 meters is covered within the entire second. It would be a fraction of a second, correct? |

i messed up anyways i converted to feet for some reason lol
i think you're right if you used t=square root of 2d/g |

your terminal velocity increases sooooooooooo
stop using crap math |

Sir, This has nothing to do with REAL sports.
Please post this somewhere else.
Thanks. |

"Sir, This has nothing to do with REAL sports."
Yes it does, this is a mathlete debate.

Like I said
Less than 1 second |

its like 1.01 seconds, you really fked that one up bens. |
|

Tell me how it takes 1 second to fall 9.8 meters then, but the person is only falling 5 meters? How would it take longer to fall 5 meters than 9.8 meters? |

Well if the object falling from 5m is a feather and the object falling from 9.8m is a rock, then it'd take longer for the object falling from 5m to reach the ground |

It depends if they land feet first or if they land on their stomach. |

velocity and acceleration are different bens. velocity is change in displacement over time, acceleration is change in velocity over time. You're not falling at 9.8 meters per second the entire time. |
|
|
it would beeeee
slightly over 1 second

What if they jumped up before they fell? |
