Work is expressed in Joules, or a Newton meter. So to lift the log five meters would take 25 kiloJoules.
That depends how high you lift it.The work is mgh (mass x gravity x height). If the mass is in kilograms, gravity is in newton/kilogram (Earth gravity is about 9.8 newton/kilogram), and the height is in meters, then the work will be in joules.
The amount of work done is determined by an object's force times the displacement. In this case it is 28 Newton meters, or 28 Joules.
350/5 = 70 Newtons. Force is not a function of distance but work is
1 newton-meter = 1 joule

200 newton-meters per second = 200 watts.

In this case, work is the product of force and distance. (This assumes that both are in the same direction, and that the force doesn't change.)
2 Newton-meters
Work = force x distance = 20 x 2 = 40 newton-meters = 40 joules
the 100 grams is equal to 1 newton body exerts 1 newton force to lift 100grams. -by alok
