A fire hose ejects a stream of water at an angle of 33.3 ° above the horizontal. The water leaves the nozzle with a speed of 25.7 m/s. Assuming that the water behaves like a projectile, how far from a building should the fire hose be located to hit the highest possible fire?
First, that is 3 not 2D you're looking at. That depression by the ball is orthogonal to the 2D plane of the tarp. And that's in the third spatial dimension. In fact, even the tarp is not 2D as it's the object that depressed, in the third coordinate. My image, which has served me well, is that space compacts [See source.] as we draw closer to the source of gravity (i.e., mass, energy, and/or stress). So out and away from a source we have dS dSi + dSj + dSk but in closer we have ds dsi + dsj + dsk. Time is disregarded here, but it is a dimension. In other words, the metric for space compacts from dS to ds dS as we draw closer to a source. And that creates a potential energy well, which tends to more negative as we close in on the source. And from HS physics what do we know about losing PE, from the conservation of energy law the PE is converted into kinetic energy. In other words, the object accelerates; you know, like acceleration due to gravity.
outer cv joints make a clicking noise at wheel speed while making sharp turns. inner cv joints make a similar clicking noise while driving straight. look to see if the cv boots are torn open. but i think since you said a pop or click ( singular) and when hitting a bump that it is more likely a lower ball joint with excessive play.
