ACD case slides along a floor in the positive direction of an x axis while an applied force a acts on the case. The force
is directed along the x axis and has the x component Fax = 9.0x - 4.0x², with x in meters and Fax in newtons. The case
starts at rest at the position x = 0, and it moves until it is again at rest. (a) At what position is the work maximum, and (b)
what is that maximum value? (c) At what position has the work decreased to zero? (d) At what position is the case again
at rest?
