➖Here v= constant
➖so f=µN will be 0 since {Net force along horizontal is 0}
⏹️µ= coefficient of friction.
⏹N= normal or the perpendicular force pushing two objects together.
⏹️F=ressistive force of friction.
✔️Using FcosΦ=µN
substitution if values of all the forces is done.
➖➖Then finally solving we get :-----
⏹️F=µmg÷cosΦ+µsinΦ
Substitute for:---
⏹ w=Fd
and hence the work done will be :-----
⏹µmg*d÷cosΦ+µsinΦ
