Ok, we have a physics project we need some good ideas for. It has to be a self propelled car or airplane using no kits or chemical reactions. These are the specifications:
Max Height: 1.0 m
Max Width 1.0 m
Max Length 1.0 m
Max Mass 4.5 kg

No explosives, hazardous or dangerous materials can be used. No chemical storage of energy may be used. No biologically active components (no animal power).

Also, we cannot built a launcher it must be SELF PROPELLED,

If you answer this thank you so much. And please only serious answers, we aren't looking for any funny guys.

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.

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
