Quarkcharmer, you have been great. I have been helping my son, this is an online exam.
He just told me that he was able to solve with your help and he got it correct.
Really appreciate you taking the time to help out a couple of beginners, your patience is appreciated.
Now I have a major appreciation when posters such as yourself take the time to present the equations in a clear format. Much more difficult than I imagined.
VERY rough on my Algebra - the first equation would now be
1.8 x 2t^2 = 200,000
BTW, great handle.
First, how in the world are you able to enter these equations so clearly?
If I understand, the first equation is now 200,000 = (Zero x t) - 1/2 (1.80 x t^2). Concerned unit of measure for A is not correctly represented in my step of the equation
Yes, makes sense at zero. Though the question is based on a volcano, so I am thinking initial velocity would be when it leaves the cone of the volcano.
Unfortunatley, I am not familiar (or sure) how to use the formula you provided.
Homework Statement
Material ejected to a height of 2.00 x 10^5m. Acceleration of gravity is 1.80 m/s^2, find initial velocity
Homework Equations
v (zero) = v - at.
The Attempt at a Solution
Seems as though I am missing something since I don't have time or velocity, yet I have...
Got it, and my highest gratitude for the Physics Forums team assistance.
ehild, loved the jpg; will actually get a few hours extra sleep with the assistance from the forum.
Thanks to all
ehild,
Your advice is well taken - guessing you may be a Professor with first hand knowledge.
I won't be able to be a long term solution, just wanted to kick start his first weeks. You are correct, I cannot replace his Prof.
I appreciate your detail and will be able to work with it...
PeterO,
I won't begin to attempt to use words to explain my ignorance, so this is the problem directly from the worksheet:
PROCEDURE
1. Use appropriate math processes to provide missing information in the table and requested information in the problems following.
DATA -- Be sure to...
ehild,
This is an introductory Physics class at his Community College. First class was last week and he has not picked up the book yet. He "lost" his notes. Hit me at 8pm tonight with the problem, now it is 1am. Class at 9:30am so I wanted to get him some confidence before he turned in...
PeterO, no question you are trying to help. Problem is I am just now re-learning the concepts and terminology.
I read the "why aren't I getting anwers" post, and thankfully you were willing to provide asssistance. Clearly, I am not ready to be posting on this forum since I am trying to...
I was able to figure out the process for the Resultant through a convoluted process of using a Vector Adding script then backed into the steps with other data I found on the web.
This actually helped to have the answer since I was able to trial/error the process. Next fun task was building a...
Well, Vector A is a measure of 26a, with A being a variable which could be pounds, millisecond, etc and it is at 35 degrees.
Am I on track?
It has been 40 years since I finished college, and now taking a crash course in Physics since my son has his first class. He has given up out of...
