I don't understand, it says that the tank is half full.

"A cylindrical tank of height h is half full of water, all of which is to be pumped up over the side of the tank. If the total mass of the water is m, how much work must be done by the pump?" At first I tried this the easy way by simply assuming that I need to pump a mass m up to a height...

That would be the graphic way, but a) requests you to solve it algebraeicly.

Is the speed of the second puck after the collision: v = 0,9191 i - 1,613 j ?

Heres the problem. A bridge span is 5m high and 20m long. Find the vertical force and the horizontal thrust on each of the piers P in terms of weight suspended from the center of the span. I really hope you can understand the geometry of the problem without the drawing(there was a drawing...

Particle statics- Three forces on force table I have the following problem: Three forces of magnitude 10, 25, 30 dynes are in equilibrium on a force table. a) find the angles between the forces algebraicly. b) find the angles graphically Here is how I attempted to solve a): I...

Im pretty much a physics amateur, I actualll study medicine, but now I am pursuing physics as something of an intensive hobby. I really like to be able to understand the universe a little bit more with everything I learn. This new love for physics is due to the Feynman lectures, they are great...

Thanks very much to all of you guys, what you wrote really put some things in perspective for me. I have the feeling that there are two things that make my frustration. 1) I tried too much, too fast. When I started studying a few months ago it was the basics of derivatives and integration...

I really really want to be able to understand as much physics as I can, I have the stupid feeling that the way I see the world is a bit "fuzzy", and everytime I understand something new about it its like I am relieving an itch, only a little bit at a time. Im generally interested in science...
