A force F with arrow= (6xi+ 5yj), where F with arrow is in newtons and x and y are in meters, acts on an object as the object moves in the x direction from the origin to x = 5.32 m. Find the work W = the intergral of F with arrow · dr with arrow done by the force on the object.
Homework Answers
The y component is orthogonal, no work in the vertical direction
Work = integral [ F∙dr ]
Work = 6 * integral x.dx [from 0 to 5.32]
Work = 6 * x2/2 [from 0 to 5.32]
Work = 3 * 5.322
= 84.9 Joules
