It would not be possible for ALL sewer pipes underground to slant downward. Are pumps used? Unless you know the answer, don't answer, because your guess would be no better than mine. Please answer only if you are sure that you know. If pumps are used, I have never heard of them "breaking down" and causing a back up. And they would almost certainly "break down" every once in awhile.

A projectile is fired with an initial speed of 30 m/s at an angle of 60 degrees above the horizontal. The object hits the ground 7.5 s later.
-to what maximum height above the launch point does the projectile rise?
-what are the magnitude and direction of the projectile's velocity at the instant it hits the ground?
ur playing right field for the baseball team.ur team is up by one run in the bottom of the last inning of the game when a ground ball slips through the infield and comes straight toward you. As u pick up the ball 65m from home plate, you see a runner rounding third base and heading for home with tying run.u throw the ball at an angle of 30degre. above the horizonal with just the right speed so that the ball is caught by the catcher, standing on home plate, at the same height as u threw it. As u release the ball, the runner is 20m from home plate and running full speed at 8m/s.Will the ball arrive in time for your team's catcher to make the tag and win the game?-give times

anyhow so energy can be converted to matter and vice versa. So I guess the real question is wich came first the chicken or the egg? But thats not my question my question is what happens when C changes like say when energy gets pulled in by a black hole like the one they are attempting to make at the CERN project? IF C becomes a higher number when approching a black hole and we make even a small one on the earth wont alot of energy thats going twoards the black hole become more amplified in some way and possibly cause a big explosion possibly? I mean the EM fields around the partical accelerator they are gona use to make these black holes will be rather large... Sure am glad they are doing these test in europe and not america. Fools lol.
