A body of mass `2kg` is resting on rough horizontal surface. A force `20N` is applied to it for `10s` parallel to the surface. If coefficient of kinetic friction between the surfaces in contact in `0.2.` Caluculate (i) work done by applied force in `10s`. (ii) change in `KE` of object in `10s`.
Take `g=10m//s^(2)`
