Question

A force in the +x-direction with magnitude F(x)=18.0N−(0.530N/m)x is applied to a 7.60kg box that is sitting on the horizontal, frictionless surface of a frozen lake. F(x) is the only horizontal force on the box.
If the box is initially at rest at x=0, what is its speed after it has traveled 17.0m ?
v=?
