Yep, when I first read it though I didn't think it specified that it started and stopped at rest.

Hmmm, after looking at this problem, does it not require that his t1=t3, or am I wrong? I get the right answer if I assume t1=t3 I think.

An object doesn't have a fixed gravity, it has a fixed mass. The force felt between two masses is described by the law of universal gravitation: F=G(m1*m2)/r^2 Where G is the gravitational constant, more or less that "universal rate" called a constant that you were asking about: G=6.67398 ×...

Hi guys, I'm currently an undergraduate physics major with a physics concentration and electrical engineering (ECE) minor, but I'm considering switching to a second discipline concentration and ECE minor. I love both physics and ECE and almost have to fight myself to not just keep adding...

Yes, pounds is a force in this context and PSI is pounds per square inch, which is called a pressure, or force per unit area. The formula for this is P = F/A and therefore PSI = (Pounds)/(Inch^2). The reason it is PSI instead of just pounds is because of how the pressure changes with respect...

Just for fun I made some measurements using a computer program. The maximum difference between the values of the two functions at any given point is 0.005321, and it occurs four times, at pi/5, 4pi/5, 6pi/5, and 9pi/5.

I was working a physics problem with two radio beacons spaced d=20 m away, each +/- d/2 away from the origin in the y-direction. They were broadcasting in-phase waves of 0.5 m wavelength, and there was a plane flying in a radius r=3*d=60 m circle with a radio that was cutting in and out due to...

Actually I was able to use a different graphing application and turned the resolution way up by zooming in, and you're right, they are just a hair different. Amazing. Thanks for your help! EDIT: Turns out they are only ~0.0035 apart from each other at the widest spot of divergence (near 0.5...

Oh, that's interesting. Thanks for the response. The graphs appear to overlap exactly, but of course there could be very minor differences that the resolution can't resolve. Are you positive it's the expressions that aren't equal and not the calculator's approximation of floating point values...

Homework Statement While doing a physics assignment today, I came up with an expression in my answer that appears to be equivalent to sin(θ), however, i couldn't find a way to manipulate the expression to prove that it was. Could anyone point me in the right direction as to a way that I could...

I'm not sure what you mean, could you clarify?

Disagree. It can be very useful and appropriate in certain circumstances, and it's good that the law allows you to do it in most states. In most cases, the shame should go on the person who makes inappropriate, illegal, or incriminating comments, but only acts differently if they knew they're...

Well, first off, your education will count for a lot--especially being a physics and math major. My recommendation would be to get as much research experience as possible while in school, and have a research section on your resume in place of work. In addition, be absolutely sure to include...

You have to go ABET--if you don't, I bet you'll regret it. Most engineering firms won't hire someone as an engineer if they didn't attend an ABET accredited program. In fact, it's probably not even called Computer Engineering, it's probably Computer Engineering Technology; so, even the degree...

Math is about as cumulative as it gets. Best to learn to enjoy the repetition and master the subject at hand, as you will use every single aspect of it down the road. Maybe not in your next class, or the class after that, or the class after that, but then you'll run into classes that expect...
