A force $=(4\mathrm{.}4$N$)(9\mathrm{.}80$ N$)$F$=4\mathrm{.}4$Ni$^-9\mathrm{.}80$ Nk$^$ acts on an object of mass $1\mathrm{.}00$kg$1\mathrm{.}00$kg as it moves in the $$y direction at a speed of $7\mathrm{.}2$ms$/7\mathrm{.}2$ms $.$ At this instant, what is the rate at which the force is doing work?
