5.11 A body constrained to move along the z-axis of a coordinate system is subject to a constant force F given by F = −iˆ+ 2 jˆ+ 3 kˆ N where ˆi, ˆj, kˆ are unit vectors along the x-, y- and z-axis of the system respectively. What is the work done by this force in moving the body a distance of 4 m along the z axis?
