1) trebuchet\n2) a very large-bore cannon\n3) JATO (rocket packs)\n4) any one of several acceleration techniques used by\n   Wiley Coyote in his pursuit of the \n   Road Runner -- the large elastic band\n   stretched across the highway comes to\n   mind :-)

Read Newton's 3rd law of motion.\nAlso, use F=ma to figure out your acceleration.

You have miles per minutes, and you want to convert it to miles per hour.  Set it up as fractions so the units cancel out, like this:\n\n1mile/8minutes * 60minutes/1hour  Now the minutes cancel and miles/hour is the final units.  Now just do the math.  60/8 = 7.5 mph.

120mi / x mph = 120mi / (-2x mph) - 3hrs\n120/x = -120/(-2x) - 3\n120/x = (120 + 6x)/(2x)\n(2x)(120) = (x)(120 + 6x)\n240x = 6x^2 + 120x\n6x^2 - 120x = 0\nx^2 - 20x = 0\nx(x - 20) = 0\nx = 20\n\n20 mph

Find a grassy park or golf course.  \n\nWear some blue jeans.\n\nBring a friend.  \n\nStart with the bicycle seat height too low at first--set it so that your legs reach the ground while seated.  Later, you will set it high so that your legs straighten while pedaling, but save that for next week.  ;)\n\nGet the friend to push you very quickly while you're upon the bike, on the nice soft grassy area. \n\nTRY TO GO FAST!\n\nSlow bikes are nearly impossible to balance.  So, a bit of speed helps.  Landing on the grass won't really hurt, so this can let you go fast enough to balance easily.  \n\nIn all 50 states, it is legal to ride upon the sidewalk any time you feel endangered by the car traffic.  \n\nIt is also legal to ride upon the sidewalk whenever the cars are going fast and they have only one lane each direction.  \n\nIt is not a good idea to ride upon a sidewalk because many cyclists are hit by cars as the cars suddenly turn right and drive across the sidewalk and into a parking lot or side road.  So, it is usually much safer to ride on the street.  \n\nA neighborhood street is usually better than a major street.  \n\nJudge the desperation (mood) of the drivers, and do always make eye contact with a driver who might turn right--right over you.  \n\nIf a car hits you from the side, it is considered that the cyclist ran out in front of the car.  However, if a car hits you from behind (very rare!) then it is nearly certain to make you a lot of money.  Most car drivers know that rear-ending someone can cost a fortune.  This is another reason not to ride on the sidewalk.  \n\nHowever, if you're sharing a lane with the cars, make sure it is wide enough on the right to allow you some room.  If not, take the whole lane, but use a rear "blinkie" and follow a somewhat erratic (not quite straight) path so that you're easier to notice by the car driver.  \n\nHave fun!

Zero mph.  You STOP when you hit the ground.

Depending on the size 3-5 mph

use extra speed and use more energy at the start

Get off the computer and get outside and use good old trial and error.  Build a ramp of dirt--it may be easier to make a pile of rocks (or whatever else you have in your area) and cover it with dirt.  Jump your bike off it and then adjust it as needed.  Buy a mountain bike video (The Collective, Kranked series, etc) and check out how they build theirs.  They will be bigger and the lips will be more vertical, but you can scale it down.  Also check out photos on online forums (MTBR, NSMB, ridemonkey, busted spoke, etc).  People post their dirt jumps all the time.\n\nIf you know of any BMX jump tracks, check those out.  But realize that a MTB wheelbase is longer, so the curvature of the ramp/lip needs to be a larger diameter.\n\nIf youre only going for 3' of air, you can probably land flat or build your jump so that you land on a down-sloped transition.  When you progress bigger than that, you will probably build your own transition exactly where you need it, and at the angle you need.\n\nCheck out Bellingham, WAs dirt jump park--my buddy helped develop and build it.

The easiest way to do this would be to remove your chain. This will let you pedal and not go anywhere. You will have to find a way to make the bike stationary so you can keep your balance while you're on it. I suggest removing the front tire and building a stand to prop the front tire frame in.  Make the stand level with the back tire so it will be exactly like riding a bike when you are on it.

get smaller gearing and itll make it harder to pedal a little bit but youll get more speed so yeah or u could just get lighter parts so easier to pedal just make sure everythings tight or ulll get screwed over so yea if u need to know anything else bout bike email me crashnbad@yahoo.com

It will take you 10 hours. \n\nIf you ride only 2 km ever hour, then after one hour you will be 2 km closer to your destination. Take 20 and divide it by 2, and that gives you 10 hours. \n\nIt doesn't matter for your question, but that's a pretty slow bike! A person could walk faster than that.

First off brake before you get to the turn and coast or pedal through it... You never want to brake in a turn... Things can get heck a ugly at high speeds if you do... I have the road rash to prove it...\n\nWhen braking, my advice is to use both your brakes... Focus on using the front one the most tho. Your braking power should be applied about 80% in the front and 20% in the back. Lean back as you brake to allow your front tire to get better grip and prevent yourself from flying over the handlebars...\n\nIt takes time to get comfortable using your front brake... Your first instinct is to lock up your back brake and go into a skid, but doing this actually makes you go faster and you loose a lot of control which can cause you to crash... 80% of your braking power is in your front brake so use it! \n\nI think it is a good idea to practice if you are not used to using your front brake... On a flat stretch of pavement make a chalk mark... Then get up to speed (15-20 mph) and when you get to the mark see how fast you can stop without skidding... Its a good exercise... Sooner or later the moving your body back as you brake with your front brake will become natural and when you get in a pinch you won't even think twice...\n\nI hope this helps... Have fun biking!
