Stuck with an acceleration problem

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving an object with an initial velocity of 50 m/s traveling straight up, with gravitational acceleration set at -10 m/s². Participants are exploring how to determine the time it takes for the object to go up and down, while grappling with the variables involved in the kinematic equation.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the use of the kinematic equation x = 1/2at² + vi*t, noting the challenge of having two variables, x and t. There are questions about the definitions of these variables and which one to solve for.

Discussion Status

Some participants have offered hints and clarifications, such as noting that if the object starts and ends at the same position, the displacement is zero. There is acknowledgment of confusion regarding the initial setup of the problem.

Contextual Notes

One participant mentions that the problem is part of a larger context, indicating that this specific question may not be isolated. There is also a note about a potential misunderstanding of terminology, as one participant clarifies the phrase "into all" as a typo for "initial."

I know this is quite simple question.
An object has an into all velocity of 50m/s it's traveling straight up. Assume g=-10m/s^2 how long does it take to go up and down?

I put these numbers into x=1/2at^2+vi*t but I still have 2 variables. X and T. Idk what to do.

Well what does the variables x and t define? Which one would you like to solve?

Hint: If you start and end at the same position, your displacement is zero.
 
Oh jeez.. Thank you. This is just a step in a bigger problem and I forgot how to do this part. Thank you rockfreak!
 
an into all = initial Must be some sort of code
