Problem
A block is pulled along a horizontal frictionless surface from x=0 to x=10m. The force acting on it satisfies the following conditions:
(a) Draw a labelled sketch of one possible F versus x graph consistent with the above information.
(b) Determine the magnitude of F2 that satisfies condition 4.
(c) If, instead, the magnitude found in part (b) were doubled while all other conditions remained unchanged, calculate the new net work done and state whether it is positive, negative, or zero.
