I mean, you couldn't use the elevators even if you wanted to, because those return to the lobby automatically. Is someone supposed to just carry the guy down the stairs?
Installing appears at the top of the screen. 2 Immediately upon seeing the blue bar, press CtrlF11. If you do not press CtrlF11 in time, let the computer finish starting, and then restart the computer again. NOTICE: If you do not want to proceed with PC Restore, click Reboot. 3 Click Restore and click Confirm. The restore process takes approximately 6 to 10 minutes to complete. 4 When prompted, click Finish to reboot the computer. NOTE: Do not manually shut down the computer. Click Finish and let the computer completely reboot. 5 When prompted, click Yes. The computer restarts. Because the computer is restored to its original operating state, the screens that appear, such as the End User License Agreement, are the same ones that appeared the first time the computer was turned on. 6 Click Next. The System Restore screen appears and the computer restarts. 7 After the computer restarts, click OK. Good luck! Update: Even if the blue Dell bar doesn't pop up during POST (this is before you see anything related to Windows), pressing Ctrl+F11 at that point doesn't do anything? Hmmm If all else fails, you could install some flavor of Linux. Some links in Source(s). Again, good luck!
You should just get an OS disk, wipe it clean and start from scratch. You don't need to log in to do that.
It is much easier to do this problem if you go to this site and follow the steps to get to your problem. I started with the box titled calculation of peak height range and time of flight because of your givens. Use their formulas. If you look at this you will see that if you fired a shell at 55 degrees at 300 m/s and it landed at the same height x that you started out with it should take 50.152 seconds. But your shell only took 42 seconds, so you know the mountain shortened the time until the shell hit. So go to the box where will it land, and plug in your values and use their calculation formulas. Derive the formulas for y height from the formula y Vo*t-1/2g*t^2 t1 time to reach apogee height 8.14 sec t2 time of total flight equals 42 seconds y 1677 meters (height of mountain that shell hits in 42 sec) x1 1402 meters (horizontal distance to apogee height) x2 7228 meters (horizontal distance to where shell strikes mountain) so your x and y coordinates are : x 7228 meters, y 1677 meters hyperphysics.phy-astr.gsu.edu/hba use this link to work out your second one too.Good luck..it is pretty self explanatory at this link
before doing any thing more, be sure there is no water that can migrate into the area you are trying to solder. a drop of water in ten seconds drip will take all the heat away from the joint. when you heat the pipe, water from a long way off can suck the heat away. some people plug the pipe with something that will dissolve when the water is turned back on. Toilet paper. clay dirt. be careful what you use. Better to stop the water or blow the pipe clear. Listen to gary.
