Work

Find the work done in moving an object along a vector u=3i+2j-5k if the applied force is F=2i-j-k. Use meters for distance and newtons for force.

Short Answer

Expert verified

Work done is9Nm

Step by step solution

01

Step 1. Given information

Force vector and direction vector are given as F=2i-j-kandu=3i+2j-5krespectively.

02

Step 2. Finding Work

Work is simply dot product of force vector and direction vector.

W=F路u鈫�=(2i-j-k)路(3i+2j-5k)=(2路3+(-1)路2+(-1)路(-5))=(6-2+5)=9
