lol, no I did not read the link. But now that I have read it, I feel rather clever yet much less original.
"...This shows that the initially hot water goes faster, but of course it also has farther to go..."
Although I have my MS is in Mechanical Engineering, I wholly despise...
gradient ;)
come on guys- think about Newton’s law of cooling, the temperature differential establishes the heat transfer rate, so if you have a bigger temperature differential (water temp vs. ambient temp) you will have a faster heat transfer gradient. Here's the fun part. Since the hot...
Got It
Thanks mukundpa and zzzzz,
The sin cos thing was a typo but the velocity difference is essential to conserving the location of the center of mass of the system (ie. conservation linear momentum). I can't believe I missed that,
Thanks
Ok, don't ask why I was doing this dynamics problem from an old textbook, but, I cannot get the answer to match that in the back of book and it's a simple problem.
Here it is, a cannon weighing 400 lb, fired a cannon ball weighing 10 lb, and had a muzzle velocity of 200 ft/s. For a 10 degree...
