Time varying force horizontal F=K(0)t is...

Time varying force horizontal `F=K_(0)t` is applied on a block of mass placed at rest on a rough horizontal surface ( `mu` is coefficient of friction).At a time `t=(3 mu mg)/(K_(0))` the acceleration of the block is given by `a =p mu g` where p=...........(`K_(0)`is a positive constant)
