Twister Buggy Parts Horse And Buggy (Dr. H Gets Pulled Around)?
Horse and Buggy (Dr. H Gets Pulled Around)? - twister buggy parts
Perhaps the oldest and most famous "Twister" brain "in classical physics. Which is correct?
a) If action reaction is always the same, the horse can not move your car, because the action stopped the horse into the carriage just by the reaction of the vehicle on the horse. The car pulled back on the horse as hard as the horse pulls forward on the car, so I can not move me.
b) The horse pulls forward slightly harder on the car when the car moves on the horse, moving, etc..
has c) The horse pulls the cart before the time to respond, then go ahead.
d) The horse can pull the car forward, unless the horse as the car weighs.
e) The force on the car is as strong as the force on the horse but the horse is tied to the ground by the feet, while the buggy is free to roll on the wheels of the year.

Oh, that unlike the past, is a real problem, F = ma
kind'a like the Space Shuttle, on a smaller scale.
Force applied to the mass of the car (until the car gets up to speed) is the acceleration of the car.
(and) too many horses.
the (E).
Okay, I must watch this.
Force = mass * acceleration. F = ma
* = Effective distance. W = FD
So if you go, a constant speed, more power.
because there is no acceleration.
and no work, because it is a strength.
even if the wheels are really lousy sticker + + does not rotate.
and constant pressure is needed to keep the same speed, so that no force, and therefore do not work.
poor horse.
take 1 horse to keep horses and 0 Force 0.
not fair at all.
The horse pulls the wagon. There is growing.
Logically, you know that the horse can pull the car, the answer is "e)" The system is not limited to horse and wagon is exercised, the horse also a force on the ground, the buggy exerts a force on earth and the earth has an equal and opposite force on the horse and cart, etc., if you look at the direction and strength of all forces, including friction, you'll see that the horse can actually move the car.
When the earth was not part of the system, and the horse and the car is just floating, then yes, the horse must be given no opportunity to correct the car?
Helmut is right
Answer as to overcome stiction forces buggy at rest the horse. A horse must exert enough force greater than the friction forces created the car to move the car. Bonus Comment: The proposal involves the retention of the dynamic friction forces are generally less than static friction forces.
