Explain how the Tractor got there.?

A raft ferry. You string a rope between the island and the mainland. Attach a raft to it. As a raft isn't technically a boat when you pole, pull or paddle the raft to the island with the tractor on it you don't break the set rules. No boat, bridge or air transportation. As the tractor is being rafted over intact it won't be built on the island.

I put this one up earlier this week, but here goes:\n\n   The blonde os driving her car down a road going toward a larger city, and she's following a truck.  She then pases the truck and motions for him to pull over.  Both vehicles pull over, and the blode gets out of her car, walks up to the truck & taps on his window.  He rolls it down and she says, "Hi! My name is Becky and I thought I should tell you you're losing some of the load from the back of your truck."  He nods and then pulls away.  Another mile down the road she motions for him to pull over again, and both vehicles pull over again.  She again gets out of the car, goes up to the truck and tells the driver, "Hi!  My name's Becky and you're still losing stuff out of the back of the truck."  He again nods and pulls away.  They're now on the city limits of the city and approach the stop light.  The truck driver passes the car and motions for the blonde to pull over, and both vehicles pull off the road.  The driver gets out of the truck, walks up to the car & motions for the blonde to roll down her window.  She does, and he says, "Hi!  My name's Randy...you're driving in Iowa...and I drive a salt truck."

When the horse exerts a force on the cart, or pulling forward, it is exerting an opposite force on the earth with its feet and this causes an equal and opposite force by pushing the earth backwards.  But because of the very large mass of the earth, that motion is not discernible.\n\nMoral of the story is do not have a smart horse, a dumb ass will do.

all you have to do is calculate the work that the engine should have done.  W=Fx meaning work equals force times distance.  The force is mass times acceleration, so it would be 10 x 9.8 (9.8 meters per second squared is the acceleration due to gravity) giving you 98 (lets round to 100 so i dont have to get a calculator or think too much because im tired, and your other data only has one significant figure anyway, if you think you need it more precise you can go get a calculator and do the work im going to show you with 98 on a calculator...)\n\nanyway, so to find the work (W=Fx) you multiply the force we just found (100N) by the distance so you get 100N x 4m = 400J.\n\nNow you know that the engine should have done 400J of work, but instead it did 500J, meaning that it did extra work, so it's not 100% efficient, so to find the percentage of its efficiency, just divide 400/500 and multiply that by 100 to get the percentage.  So its .8 x 100 so 80%.\n\nAnd if i may ask, why do you keep asking very basic questions on completely random physics topics that you would clearly not be doing all at once, and if you already did all of it, you should already know these answers?

Maybe or the truck transporting them on the "high" way lost them due to an open door,and you happened to walk underneath that road.Maybe it will stop in a few seconds:then it was a truck.\nIf it keeps on raining it will be manna from heaven for you.Your daily bread.

depends upon the PATH travelled... ISN"T IT????\nor\nWhy will the bus go there????? since the cat is already there....\nor Depends upon the size of SUGARCANE..........

(1) Balance the forces\n\nSFx = -Tsin(q) + mv^2/r = 0\nSFy = Tcos(q) - mg = 0\n\nSFx and SFy represent the sum of the forces in the x and y directions, and T is the tension on the string. This leads to\n\nTsin(q) = m*v^2/r\nTcos(q) = mg\n\nDivding the first by the second yields\n\ntan(q) = v^2/(r*g)\n\nwhich is readily solved for the angle q.\n\n(2) The centripetal force is balanced by the gravitation attraction. This says that\n\nm*M*G/r^2 = m*v^2/r\n\nwhere m is the mass of the satellite, M is the mass of the Earth, v is the speed, r is the radius of the orbit, and G is the gravitational constant. Also, given the period (T) of orbit\n\n2*pi*r = v*T\n\nSubstituting for r and solving for v\n\nv^3 = 2*pi*M*G/T\n\n(3) At the top of the hill, in order to avoid losing contact the centripetal force must be balanced by the weight\n\nm*v^2/r = m*g\n\nsolving for v\n\nv = sqrt(g*r)\n\nAny faster and the centripetal force will exceed the gravitational force (weight) and the motorcycle will lose contact with the hill.

1.  Hurl it spinning into space.  The vehicle will spin around its center of gravity, and its center of gravity will travel in a straight line.\n\n2.  Balance it on a see-saw three ways: upright, on its side, and on one end.  Each balance will define a middle plane that cuts through the vehicle.  The intersection of the three planes is the center of gravity.

TWO...but how did they get in there?

plz find car position and after \nincrement in car position and car is moving

3.36 meters.  \n\nHere's why:  find the formula for the parabola.  We know that when X is 0, Y is 4.  And, we know that when X is 2.5, Y is 0.  So the formula is:\n\nY = 4 - (4/6.25)*X^2.\n\nNow let X = 1 (half the width of the truck), you'll see Y is 3.36.

1. its final velocity depends on the direction it was heading to start off with. If it was flying in the x direction (no components in y or z) then after 4.3 seconds the x component has increased by 8.92*4.3  and the y component has increased (from 0 this time) by 1.21*4.3.\nso now you can work out the new direction (in the x direction but slightly downwards by whatever angle has a tangent of 1.21*4.3/(152+8.922*4.3) \nand using pythagoras to determine the speed.\n\n2. You can ignore the gravity as it is << the precision with which the acceleration due to the electric field is stated (I'm assuming the 106 is 10^6 = 1000000) \nso the final velocity is 3.80*2.45*1000000 m/s upwards.

I think I know why your not getting the right answer..... it's the physics thing.\n\nAny Geography questions.... anybody.... Oh well.\n\nBy the way, "Nameless", who shat in your corn flakes??

Let x be the distance he walked.\n\ntime = distance/speed\n\nso time walked + time in truck = 10 hours\n\nx/5 + x/20 = 10\n\nmultiply by 20\n\n4x + x = 200\n5x = 200\nx= 40 km\n\nCheck - he spent 40/5 = 8 hrs walking out, and 40/20 = 2 hours walking back for a total of 10 hrs.

Hmm, I've always hated algebra. The answer is; The 1st. annual 2006 Neo-conservative tractor pull on the White HOuse lawn, sponsered by Enron and the Saudi family. :) The quail hunting portion has been cancelled this year.
