harshitchaudhary2015: very thank you for your helping hand.. but my doubt is that it in the given question the rate of dissipation of mechanical energy is ask asked so why we should apply negative sign before Fv if it is already asking for loss

Anonymous: buddy actually I g.o.o.g.l.e.d it what I find given to you

harshitchaudhary2015: ok thanks
