A force in the +x-direction with magnitudeF(x)=18.0N−(0.530N/m)x is applied to a 5.60 kgbox that is sitting on the horizontal, frictionless surface of a frozen lake. F(x) is the only horizontal force on the box.

Part A

If the box is initially at rest at x=0, what is its speed after it has traveled 13.0 m ?

Express your answer to three significant figures and include the appropriate units.
