A 0.046 kg golf ball was hit with an impulsive force that averaged 8000 N. If the ball was in contact with the club head for 5.0 x 10^(-4) s, what was the speed of the ball immediately after impact?

E/c = m x c; so momentum requires a mass. without mass does momentum exists?

Any answers are great, but scientific ones, would be very interesting. I said I didn't think they could, but as I've never tried it, who knows?

And if you could give the density at pressures of 100, 200 and 220 bar, also 125 and 175 deg C, that would be great !

I have leen lead to believe that photons exist and have a finite mass, although they can also have the properties of a wave.

Anything approaching the speed of light should theoretically have infinite mass, so photons theoretically have zero mass(?).

... you can guess where this argument takes me. Where am I going wrong?

Hi-
Can someone please answer this for me? How do you show that if the force of an object is always perpendicular to the velocity of the object, then the speed of the object is constant?
Any help would be appreciated!!

gravitational force between them. Which means that any two objects in the universe pose forces on eachother. Just because the forces are neglegable doesn't mean they don't exist. Besides, Einsteins thoery of general relativity shows gravity bending space-time. Now the Q still stands: does the atoms mass produce the gravitational effect or does the gravitational effect produce the atoms mass?

I've heard of the two slot experiment.

My experience of this world leads me to have some sort of understanding waves (as on the sea) and of particles (smaller versions of something I can hold in my hand).

I am still having trouble, however, in how the two can be interchangeable or exist at the same time.

The double-slit experiment explains the nature in which we've observed light acting as both particle and wave. By conventional science doing both simultaneously is impossible but that's exactly what happens. But really we all know we call particles of light photons and I'm aware that they are emitted from within the atom where a dissipation of energy can be observed without any fluctuations in mass. But my question still stands: where does it come from elctrons, protons, neutrons, quarks, neutrinos. And what exactly is a photon, when the double-slit experiment shows how a single photon shot through a single hole produces wave patterns on a second hole when the second hole is not the the trajectory of the fired photon. More weird is how the photon produces itself on a phtographic slate in its rightful position. First it's a particle, then a wave, and then a particle again. Apparently light doesn't follow the laws of conservation of mass and energy.

There are an awful lot of tiny atoms and each should fill up a finite volume of space. They are supposed to be travelling around the nucleus in a sort of perpetual motion.

Even with the electrostatic charges trying to separate them, shouldn't there be some collisions? What would happen if they do collide?

Is it a particle or a wave? Does it require a medium or is it one? Has anyone truly discovered the source of light? Or is it as fleeting as its velocity?

Asking a question raise the curiosity to know certain facts. The question also suggest an answer and help people to find out a solution. Negative marks for question discourage the habit of enquiry and hence the qualitative questions. There is no answer if there is no question. Does it seem desirable to award atleast some marks, may be lesser than answer, for a question?
