The part I'm having trouble with is setting up the problem and plugging in the givens.

Homework Statement A 45-Kg girl is standing on a 150-Kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.50m/s to the right relative to the plank. a)What is her...

Why can't we tell the mass of electron neutrinos, mu neutrinos, and tau neutrinos?

Is this same answer used for gluons and gravitons.

Why doesn't the Higgs field give photons mass?

I can't answer question number one because nobody knows and their is no possible way to test that yet. As for question number two the answer is yes. Dark matter and dark energy make up 95% of the universe while the matter we know makes up the rest.

You would be in equilibrium when you are static but as soon as you begin to accelerate upward you are no longer in equilibrium

Well let's say that you are having an interview for a job. In order to meet this person for the hypothetical interview you would have to go to the corner of 25th st.(length) and MLK(width) then up to the 6th floor(depth), then for the fourth dimension you need to know what time the interview...

I remember hearing someone say that due to the probability factors of quantum mechanics that if you walked into a wall for an infinite number of times that one of those times both the molecules in the wall and in your body would be arranged in a way that you would theoretically be able to pass...

Thank you for your explanation, i am having a hard time understanding the "butterfly effect" i can understand how in the early state of the universe any little change could have had a drastic impact on the state of the future universe but does the butterfly actually have an impact on air...

The force making the normal force increase as you push down is created by the surface you are standing on. Let's say you are standing with 10N of force on a surface. As you increase the force to say 20N to jump, the surface also increases its force to 20N.

Could you help me understand the difference between entropy and chaos because i have been thinking they are one in the same.

Normal force is not an actual force but more of a pseudo force such as centrifugal force. The normal force is more of a supporting force that prevents you from being pulled directly to the core of the Earth. The normal force increases because of the weakness of gravity and your ability to...

From what i understand quantum mechanics has large part to do with probabilities. So is it valid to say that if i walked head on into the wall in my room for an infinite period of time that eventually i could be able to walk straight through it? Also is there a way to calculate a simpler version...

When your talking about a static object, such as you standing on the sidewalk then the gravitational force pulling you down is equal to the normal force pointing up. When you jump in the air the normal force overcomes gravity and you are lifted in the air. When you come back down to Earth after...
