Kinematics problem, don't know how to find unknown variables

Click For Summary

Homework Help Overview

The discussion revolves around a kinematics problem involving a rocket launched vertically with an initial speed of 500 m/s. Participants are exploring how to find unknown variables related to the rocket's motion using the provided equations of motion.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to apply the equations of motion but expresses uncertainty about how to solve for the unknown variables, particularly time (T). Other participants question the clarity of the problem and the assumptions regarding the context of the rocket's launch.

Discussion Status

The discussion is ongoing, with some participants seeking clarification on the specific question being addressed. There is an acknowledgment of the need for more information to accurately interpret the problem.

Contextual Notes

Participants note the ambiguity in the problem setup, particularly regarding the environment in which the rocket is launched, which could affect the interpretation of the variables involved.

Homework Statement


A rocket is shot straight up with an initial speed at 500 m/s.


Homework Equations


The equations the teacher went over beforehand were

Yf = 1/2 A(T)^2 + Vi(T) + Yi
Vf = A(T) + Vi

The Attempt at a Solution


So far I have

Vf = (-9.8)(T) + 500 m/s
Yf = 4.9T2 + 500T + 0

...and I have no idea how to go about solving for the rest of the unknown variables. It seems like I need T somehow, but I don't know how I can get it from the information given.

What is the question?
 
Oh, sorry. Guess I didn't make that clear. You basically just have to find all the variables in the equations.
 
I still do not know what is the question.
If you have a rocket with velocity of 500m/s, you can be anywhere in this universe.
Maybe on any planet.
