A block is initially at rest on a horizontal frictionless surface when a horizontal force in the positive direction of an axis is applied to the block. The force is given by `vecF=(1-x^(2))hatiN`, where x is in meters and the initial position of the block is `x=0` the maximum kinetic energy of the block is `(2)/(n)J` in between `x=0` ad `x=2`m find the value of `n`.
