Homework Help Overview

The discussion revolves around a problem in projectile kinematics, specifically focusing on calculating the velocity of an object thrown horizontally at a given speed after a certain time interval.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the need to consider forces acting on the object and question whether the scenario involves projectile motion due to the lack of vertical velocity information. There are inquiries about the effects of gravity and the adequacy of the provided data for a complete analysis.

Discussion Status

The conversation is ongoing, with participants offering insights and prompting further clarification from the original poster. Some guidance has been provided regarding the need to consider forces, but there is no consensus on the interpretation of the problem yet.

Contextual Notes

There is a mention of the original poster needing to provide an attempt at a solution, indicating a homework context that may impose certain constraints on the discussion.

I know that an object is thrown at a certain initial horizontal speed (m/s). I need to calculate the object's velocity (magnitude and direction) after a certain amount of time (seconds.) How would I do this? What formulas would I use? The actual question is: a calculator thrown at initial horz speed of 24m/s and calculate velocity(mag &direction) after 4 seconds.

hi triggerhorse, welcome to PF

generally you have to give an attempt at a solution and people will offer help...

I would start by writing the forces on the calculator
 
Kinematic equations.. There is no acceleration in this case.
 
based on the question though i doubt it, i'd assume it experiences gravity... triggerhorse can you elaborate?

But only horizontal velocity is given, I presume its not projectile motion.
Don't think this much data is enough to describe projectile motion.
 
Thanks for your help so far. I am going to get help at school today.
