Finding velocity equation for object moving in 2 dimensions

Click For Summary

Homework Help Overview

The discussion revolves around a problem involving a 4 kg object moving in two dimensions, with a focus on its velocity and the effects of a constant force. Participants are examining the relationship between acceleration, velocity, and force in the context of the problem.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the original specifications of the problem, particularly the use of acceleration instead of velocity. There is a discussion about the implications of stating an object's motion in terms of acceleration versus velocity, and the need for clarity regarding the direction of the applied force.

Discussion Status

The conversation is ongoing, with some participants expressing confusion about the problem's formulation. There is a recognition of the need for clearer definitions and assumptions, particularly regarding the direction of the force and the correct use of terms related to motion.

Contextual Notes

Participants note that the problem's wording may lead to misunderstandings, particularly in mixing terms related to acceleration and velocity. The original poster acknowledges the confusion and attempts to clarify their intent.

Travelling at 40m/s, right?
along the x-axis at t=1 is influenced by a constant force of 20N.
Which direction does the force act?

Which direction does the force act?

Its acceleration is 40 m/s^2 at t=1 and its moving to the right.
 
The OP says the 4 kg object is traveling at 40 m/s^2. Usually, the velocity of an object is given, not its acceleration. Is this how the problem was originally specified? 'Traveling' implies velocity, otherwise, one would say an object is accelerating at X m/s^2.

Yes, I meant accelerating, I apologize. I "made" this problem to see what I could do given the acceleration

In specifying a problem, you can't mix cause and affect like this. You can either state the acceleration (and ask for something which can be deduced from that, like position, velocity..) or you can specify forces and let the acceleration be deduced.
And you still haven't said which direction the 20N acts in.
 
Nevermind all, this is a stupid, poorly stated question. I apologize
