An object, constrained to move along the x-axis is acted upon by a force F(x) where = a = 5 N/m, b = -2 N/m
F(x) = ax + bx?
The object is observed to proceed directly from x = 1m to x = 3.0m. How much work
was done by the object by the force? Does the process of integration take into account
the fact that the force F(x) changes sign in the interval.
