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) Share with your friends Share 9 Ved Prakash Lakhera answered this 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 -77 View Full Answer
