Best ResponseYou've already chosen the best response.1eqns of motion would be Umg + m(F/M) = T and T + Um(F/M) = mg => Umg + m(F/M) + Um(F/M) = mg the value of F that am getting is not right ! ;)

Best ResponseYou've already chosen the best response.1From WFr2F'Fr1=0 we get F=g(M+2m)(1+u)(1u) From F'mgFr2Fr1=0 we get F =g(M+2m)(1+u)/(1u)
