As you do more physics, you will eventually come to the realisation that mechanical energy conservation is a good place to start when... -
Lunar Manatee replied to the thread Slight Confusion in Introductory Mechanics (Dynamics Problem).I am thoroughly impressed! I had never thought of analysing it in such a way!

I never said that the acceleration changes signs. There is ambiguity as to the object's state of motion for ##t<0.## The statement of...

Lunar Manatee replied to the thread Slight Confusion in Introductory Mechanics (Dynamics Problem).I am familiar with linear non-homogenous differential equations, just didn't really have the wherewithal to confirm it that way; but I...

The acceleration need not and does not switch signs. If we extended the scenario continuously into the past, we would see that the...

Your reasoning is correct. The force does not change direction with position and, since the object starts from rest, the velocity is...

This is a one-dimensional problem. I think is it safe to assume the standard convention "to the right is positive and to the left is...

@Lunar Manatee, note that the SI symbol for the second is 's' not 'sec', so 'm/sec' is incorrect. EDITed to remove surplus information.

Lunar Manatee replied to the thread Slight Confusion in Introductory Mechanics (Dynamics Problem).yeah, I have also been arguing that for a while. but it seems *their* convention was: grams (gm), seconds (sec.) and a few other messed...

Lunar Manatee replied to the thread Slight Confusion in Introductory Mechanics (Dynamics Problem).I am guessing they meant to say it was the algebraic (is that how you spell it?) measures. just the component of the vector along the...

Lunar Manatee posted the thread Slight Confusion in Introductory Mechanics (Dynamics Problem) in Introductory Physics Homework Help.the attempt is visible in the image. my question is more... pedantic (?). if the initial conditions are to be taken into account, v_0=0...
