A body of mass 2 kg initially at rest moves under the action of an applied horizontal force of 7N on a table with coefficient  of kinetic friction `=0.1`. Calculate the  (a) work done by applied force in 10s. (b) work done by friction in 10s.  (c )  work done by the net force on the body in 10s.  (d) change in K.E. of body in 10s, and interpret your result.
