Stewart James, Calculus, Section 6.4, Page 449, Problem 5


Shown is the graph of a force function (in newtons) that increases to its maximum value and then remains constant. How much work is done by the force in moving an object a distance of 8 m?


Can someone please help us with this question. The answer we keep getting does not match the answer displayed in the back of the book.


Thanks!
