To find: The work done by the force in moving an object along a straight line if the distance is measured in feet and the force is measured in pounds.
Answer to Problem 46E
The work done by the force in moving an object is 82 ft-lb.
Explanation of Solution
Given:
A constant force F is
Formula used:
The work done (W) in moving an object along a
Calculation:
The object moves along a straight line from the point
The displacement vector is,
Substitute
Thus, the work done by the force in moving an object is 82 ft-lb.
