An object constrained to move
along the x-axis is acted upon by
a force F(x) where a=5N/m,
b=−2N/m. F(x)=ax+bx^2
The object is observed to proceed
directly from x=1m to x=3m.
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 interval.
