What is the kinematics of a constant power motion?

[LeroyR/T]

This isn't really a homework problem, but it has to do with classwork.

Homework Statement

Suppose and object is constrained to move only in one dimension and, subsequently, moves solely under a constant-power source. You are invited to provide a pedagogical discussion about the kinematics describing the motion of the object

Homework Equations

Supposed to find those.

The Attempt at a Solution

Attached my paper.


Yes, it's my first time posting and hope you all will not fault me for that. All I need help with is if yall think that this paper will suffice for this question. thanks!

EDIT: fixed

Thanks. So far this semester 2 other classmates and I have been struggling through our first year of physics. I decided to join here for the last month or 2 and hopefully for physics 2. I've seen that this is an amazing place to find information.

Anyone?

Interesting paper. I didn't go through all the math, but it looked like your approach was okay. I did see at least one small typo in the beginning of the paper:

There are four variables associated with finding describing the motion of an object

Probably deleting the word "finding" would fix it.

Also, I'm not sure what they are asking for when they say "pedagogical discussion". I guess that literally means a teaching discussion, and maybe deriving those equations is what they mean. But for me, I'd like to also see a discussion of what real-world processes might exhibit this constant power characteristic, and what kinds of real-world motions that would result in.

Can you give some examples? Do you think it would help the paper to list some of those examples? (If you don't think so, that's fair.)
