Question

Q: A Body of mass 60 kg is dragged with just enough force to start
moving on a rough surface with coefficients of static and kinetic
frictions 0 5 and 0 4 respectively On applying the same force ,
what is the acceleration ?(g = 9 8m/s2)

When the body is just able to move then                    F=μsmg=0
5×60×9
8=294Nand when the body moves under the influence of the kinetic friction then                     F+μkmg=294+0
4×60×9
8=60aor                 60a=294+235
2=529
2or                    a=529
260=8 82m/s2
