A can of bolts and nuts is pushed 2.00 m along an x axis by a broom along the
greasy(frictionless) floor of a car repair shop in a version of shuffleboard. The figure 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 Ws = 6.0 J. (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?
