CHAPTER 4 - FORCES AND NEWTON`S LAWS OF MOTION
... The basic unit of work is the joule(J) and is equal to the product of one newton and one meter. In the English system of measurement, the unit of work is the foot pound, the product of a force of one pound acting through a distance of one foot. In order for work to be done, there must be a force ac ...

... 4) gives 42 J for the work done. (b) Counting the “areas” under the axis as negative contributions, we find (for 0 x 7) the work to be 30 J at x = 7.0 m. (c) And at x = 9.0 m, the work is 12 J. (d) Eq. 7-10 (along with Eq. 7-1) leads to speed v = 6.5 m/s at x = 4.0 m. Returning to the original ...
