Halliday, Resnick & Walker — Kinetic Energy and Work: Problem 12
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. Figure 7.11 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 $W_s = 6.0\text{ J}$. (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?
