Question
(a) During the packaging process, a can of soda of mass 0.4 kg moves down a surface inclined 20° relative to the horizontal, as
shown in the figure below. The can is acted upon by a constant force R. parallel to the incline and by the force of gravity. The
magnitude of the constant force R is 0.05 N. Ignoring friction between the can and the inclined surface, determine the can's
change in kinetic energy, in J, and whether it is increasing or decreasing. If friction between the can and the inclined surface were
significant, what effect would that have on the value of the change in kinetic energy? Let g = 9.8 m/s²
