In this case, displacement is "how far you are from where you started" so I don't believe they are thinking about direction very explicitly. Probably they are just looking at the formula --> I can't say the answer is wrong, but it's not really right. I guess one thing I could do is to dissect...
Yes, do try to see if there is a TARC team near you…or start one! And you may find a team, or graduates thereof, who will mentor you. Where are you located?
Our Girl Scout troop started this a few years back and now one of the girls will be going to college for Aeronautical Engineering. They...
I would say that many job posting will require a Bachelor's Degree and if you don't have it your resume goes in the trash, regardless of how qualified you may be.
I just want to interject that while of course you want to go to a "good" school, it is WAY less important how "good" the school is compared to:
- How good a fit is it for YOU?
- Do they connect SIGNIFICANT numbers of students with actual work experiences like internships/summer jobs?
- Do they...
I asked a class of students what the difference was of velocity versus speed. The answer I was looking for was "direction" i.e. one is a vector. But a number of them said "Velocity is displacement divided by time, and speed is distance divided by time." Ignoring the second half of that...
One factor is how long it would take to get there. If you just launch and coast, it takes way longer than if you have more fuel to keep blasting and accelerate. This is especially relevant if you want to send people somewhere.
Yes, depending on the system you might hear an increased "noise floor." But listening with no music in a quiet environment is an unfair test-they are designed for use in noisy places like a plane while listening. I can't imagine problems to your hearing, it should make for less fatigue, BUT...
THAT is the most true thing! Save obsessively…well, not obsessively, enjoy life. But count how many months you could go if you got fired tomorrow-the more months, the merrier.
A friend quit one day and moved to France for a year because she felt like it. This was enabled by her yes high...
If you get an engineering degree, you get a job as an engineer.
If you get a physics degree, what will you do? Either
A) Some kind of applied physics job, or
B) Teach
If "teach" then WATCH OUT! I made that kind of change, from engineering to teaching physics and chemistry. It is VERY VERY...
Below I'm going to copy/paste a post from a similar thread, but first I want to say that for each of those job ideas you have* you should try to research what the heck those jobs are like: what do they DO? How many job openings are there and WHERE?** How do people get those jobs? A title like...

Um. At the top you have Gayle's kinetic energy = 0.5*50.8*4.20^2 = 448.05 by my calculations.
And a potential energy = m*g*h = 50.8*9.81*17.4 = 8671.25. BUT WAIT! I forgot the sled! PE= (50.8+5.50)*9.81*17.4 =9610.07
As for the brother, he has a potential energy=33.7*9.81 *(17.4-4.77)=4175.44...
Ah, I get it now, thanks. The acceleration was calculated from the velocity change, but the "200 m" stuck on as a fact…but not really calculated. So probably this would be self-consistent if the acceleration was 0.1 m/s^2 or such.
Hi Folks: I am puzzled by this problem; there must be something wrong but I can't see what...
1. The problem statement: "A runner enters the last 200 m of a race running 6 m/s. She accelerates at 0.2 m/s2 &crosses the finish line at 10 m/s. What is her time for the last 200 m?"
2. Homework...
I'll pose that as a general question, and specifically for sound waves, which Googling did not answer in a satisfactory way.
And a specific instance I'm concerned with is as follows:
- Students are using telephone cords to make waves (cheaper and much more durable than Slinkies!).
- Most...
