What Is the Speed of a Package Dropped from an Ascending Helicopter?

Click For Summary

Homework Help Overview

The problem involves determining the speed of a package dropped from a helicopter that is ascending at a steady speed. The context includes the relationship between the initial speed of the helicopter, gravitational acceleration, and time.

Discussion Character

  • Exploratory, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to apply a standard velocity equation but struggles with the correct formulation, leading to confusion about the inclusion of magnitude bars. Other participants suggest alternative expressions for speed and question the correctness of the online homework system.

Discussion Status

The discussion is ongoing, with participants providing suggestions for expressing the speed correctly. There is a recognition of potential issues with the homework platform, and multiple interpretations of the problem are being explored without a clear consensus on the correct approach.

Contextual Notes

The original poster mentions constraints related to the online homework system, including limitations on input formatting and previous success with similar questions under different conditions.

Homework Statement



A package is dropped at time t = 0 from a helicopter that is ascending steadily at a speed vi.
What is the speed of the package in terms of V_{i}, g, and t?

Homework Equations



V (t) = V_{o} + -9.8 t


The Attempt at a Solution



I thought it was the same as the normal equation for velocity such as stated above but with the different variables substituted for example:

|V| = V_{i} + gt

except i got the answer wrong, then i tried putting a negative sign on the v_{i} part but still got it wrong...help would be greatly appreciated.
 
Physics news on Phys.org
You are close. Speed is |v(t)|. Try putting the magnitude bars around your expression for v(t).
 
the magnitude bars are already there on the online hw, only the stuff to the right of the "=" sign is what I'm able to input...nvm i see what your saying...but there was another part of the question in which the plane was descending and asked the same question and i got it right without putting the '|' around v(t)

Try

|V| = |Vi - gt|

or

|V| = |gt - Vi|

tried both but neither worked...i really think it is just the stupid website that i have to do the homework on but I'm all out of chances so doesn't matter now lol thanks for the suggestions though
