the answer is 50 j
This is a trick question... If you hold a book off the ground for ten minutes, there is no motion. In order for work to be done there must be motion. So, you would be only doing work while picking up the book, and putting it down.
The work done on the book is equal to ten times the distance it was moved (in metres).

Work done is equal to Force multiplied by distance:Wd = FxdWd = 324x3Work done = 972 Joules.
1.10 meters = 3.60892388 feet.
5000 meters = 3.11 miles
Convert the cm to meters, and multiply the force by the distance. That gives you the work in joules.
100 feet equates to 30.48 meters.

a fallen treee is lifted 2.75 meters. How much work is done?
The application of 75N of force through a distance of 8 meters results in 600 newton-meters = 600 joules of work.
800 perhaps?
The product of these two numbers, assuming the force acts in the same direction as the object moves.
Work = force x distance.So in this case the work done is 25 N x 5 m = 125 joules
If it takes 150 N of force to move a box 10 meters, 1500 joules (J) of work is done. This can also be expressed as 1.5 kilojoules (kJ).
Not meters, but centimeters. Current plates move at a few centimeters (hundredths of meters) per year. The largest of these movements are not much more than one or two inches.
