Homework Help Overview

The discussion revolves around a physics problem involving the calculation of time, final vertical velocity (Vy), and horizontal velocity (Vx) based on given changes in X and Y. The context suggests a focus on kinematics, specifically relating to motion under gravity.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the units of Vy and Vx, questioning whether the provided data is sufficient for calculations. Some suggest using kinematic equations to derive time and velocities, while others emphasize the need for a complete problem statement to proceed.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem and the necessary information required for calculations. Some guidance has been offered regarding the use of kinematic equations, but there is no consensus on how to proceed without additional context.

Contextual Notes

There is a lack of a complete problem statement, which has led to confusion among participants regarding the specifics of the demonstration and the calculations needed.

Homework Statement



Change in X=0.104m/s
Change in Y=.067m/s

Find time, Vy final and Vx.

This is probably extremely simple, but I can't seem to figure it out. Once I understand how to do this one I can do the rest.

Thanks.

What are the units of Vy and Vx? Do you have enough information in your given data to deliver those units in a calculation?
 
Without further information, this is impossible. Please give the full, exact problem statement.

It is all m/s. I think I figured it out. I used a vertical equation y=vinitialy(t)+1/2(9.8)(t)^2 to find the time, then used vx=x/t to get vx, and finally vfinaly=9.8t to get the final velocity.

There is not a problem statement, these are results from a demonstration that we are asked to calculate the time, final vertical velocity, and horizontal velocity of.

Okay, but there is no way that we could know that unless you tell us. A description of the demonstration and the goal of your calculation would have helped us to help you more quickly.

Good luck in your studies!
