A variable force of 3x - 2 pounds moves an object along a straight line when it is x feet from the origin. Calculate the work done in moving the object from x = 1 ft to x = 12 ft. (Round your answer to two decimal places.)
Added by Jessica S.
Step 1
The work done by a variable force F(x) over a displacement dx is given by: dW = F(x) dx In this case, the force is given by: F(x) = 3x - 2 So, the work done by the force over a small displacement dx is: dW = (3x - 2) dx Show more…
