The main force would be the force of gravity, which is 250 pounds in this case.

to balance moment 10 feet x force = 2 feet x 200 force = 40 pounds
Something about 1550 foot pounds, or 2115 joules.
The mathematical formula for calculating work is: Work = Force × Distance × cos(θ) where: Work is the amount of energy transferred or expended; Force is the amount of applied force; Distance is the displacement of the object in the direction of the force; θ is the angle between the direction of the force and the direction of displacement.
A falling stone will increase in speed until it reaches it's terminal velocity, the speed when the downward force of gravity equals the upward force of drag, which causes the net force on the stone to equal zero, thus achieving an acceleration of zero. If atmosphere is ignored, a falling body will accelerate at 32ft/s (9.75m/s). The distance traveled in the first second would be 16 feet (4.87m), in the second second: 48 feet (14.63m) and in the third second: 80 feet (24.38m); hence after three seconds an object would have fallen 144 feet (43.89 meters) and is traveling at 96ft/s (29.26m/s).

The work done is calculated as the force applied multiplied by the distance over which it is applied. In this case, 500 lb force over a distance of 6 feet would result in 3,000 foot-pounds of work performed.
The work done is 50 foot-pounds (5 pounds x 10 feet = 50 foot-pounds). Work is calculated by multiplying the force exerted with the distance the force is applied over.
In a lever, the force applied is inversely proportional to the distance from the fulcrum. This means that the farther away the force is applied from the fulcrum, the less force is needed to lift the load. This relationship is governed by the principle of torque, where force is multiplied by distance.
6 x 150 pounds. 900 pounds of force would have to be applied.
The force a falling object exerts upon impact is dependent on the object's mass, gravity, and the distance fallen. Using the formula F = mgh, where F is the force, m is the mass, g is the acceleration due to gravity, and h is the height fallen, the force exerted by an 80-pound object falling 10 feet would be approximately 3520 pounds.
There is no difference. It is (force x distance) or (distance x force). It is usual to express torque and moment of a force in pounds-feet and work done in foot-pounds but it is not mandatory.
Newton meters (Nm) multiplied by 0.738 = Pounds-force feet (lbf ft; lb ft). Pounds-force feet multiplied by 1.356 = Newton meters.
The way torque works, these two cases give the same torque, or twisting force, to the object at the pivot point. To find the torque applied, multiply the force by the distance. Obviously this is the same in the two cases you describe.
If you push someone with a force greater than the force of friction between their feet and the ground, they will accelerate in the direction of the force applied. The person's speed and motion will depend on the magnitude and direction of the force applied.

1 kip is equal to 1000 pounds-force. Foot-pounds is a unit of torque, not force. To convert kips to foot-pounds, you need to know the length of the lever arm in feet that the force is acting on.
