An engineer pulls a cable with a constant force F=2i−3j+6kkN. The end of the cable moves from point P(1,−2,0) m to Q(4,1,2) m and then to R(6,5,5) m.
(a) Calculate the work done in moving the cable end from P to Q.
(b) Calculate the additional work done in moving it from Q to R.
(c) Find the total work done in taking the cable end from P to R.
a. (a) Work from P to Q
b. (b) Additional work from Q to R
c. (c) Total work from P to R
