Answer: The work done in the process will be 150 unit.
Explanation: The work done by a variable force is the area under force and displacement.
The work done will be integration of F.dx from 0 to 5.
∫ F.dx(0 -5) = ∫ (3x^2 -2x+10).dx(0-5)
=(x^3-x^2+10x)[0-5]
=125-25+50
=150 units .
This is the required answer
