If the box is initially at rest at x=0, what is its speed after it has traveled 17.0 m ?

A force in the +x-direction with magnitude F(x)=18.0N−(0.530N/m)x is applied to a 5.40 kg box that is sitting on the horizontal, frictionless surface of a frozen lake. F(x) is the only horizontal force on the box. Net work done on the box equals its change in kinetic energy (Work-Energy Theorem): 1/2 m v^2 = ∫ […]
