You can represent displacement vs time as X = 10 sin (0.393 t), where t = 0 corresponds to an equilibrium position. The velocity will be V = 3.93 cos (0.393t) Substitute t = 1.5 s and you should get the right answers, after rounding off to two significant figures

The equation you need can be found at http://physics-animations.com/Physics/English/gyro_txt.htm The mass will cancel out when you insert (1/2)M R^2 for the moment of inertia. r in the reference above is the distance from the support point to the rotor. wp is the precession ...

According to "classical" (pre-1905) physics, the length will be the same in both coordinate systems. They must mean according to relativistic physics, which results in the correct answer, L' = L*sqrt[1 - (v/c)^2] The meter stick will appear shorter, but the formaula above only...

He meant 'Physics' as the subject instead of 'Tamucc', which stands for Texas A&M University - Corpus Christi. He must be taking the summer physics class at TAMUCC.

Michelle: You need a book I know of. Go to any college bookstore, or BarnesNoble, and take a look at Schaum's Outline series, Physics. There are a number of titles in this series, I like the Physics for Scientists and Engineers, but that may be a bit mathematical for you, so ...

This site is just a front for liveperson Most college physics questions are not answered for months if ever. Out of "200 experts" you must have somebody who knows physics right? Guess not.

You need to get a basic math tutor immediately, or drop physics. The language of physics is math, and you are operating at an algebra I level, at best. You will not succeed. speed-1.8=30/11 speed= 30/11 + 1.8= 4.5m/s Physics comprehension will demand much higher levels of ...

The first thing you should learn about physics is that you have to provide the dimensions along with the numbers when computing physical quantities. Physics is not just arithmetic. You have not even asked a question! Why are you taking this course?
