A can of bolts and nuts is pushed 2.00 m along an x axis by a broom along the greasy ( frictionless ) floor of car repair shop in a version of shuffleboard. Figure 8-46 gives the work W done on the can by the constant horizontal force from the broom, versus the can's position `x`. The scale of the figure's vertical axis is set by `W_(s)=6.0J`. (a) What is the magnitude of that force ? (b) If the can had an initial kinetic energy of 3.00 J, moving in the positive direction of the `x` axis, what is its kinetic energy at the end of the 2.00 m ?
