yes
Explanation:
In the case of limiting friction the body moves with uniform
velocity
therefore the net force must be zero and that leads to zero acceleration.
the example is a body kept on an incline ...
the net force along the incline ( at an angle
whereas the force of friction f is opposing this tendency
but f the frictional force has a limit which it can not exceed.
therefore
therefore m.a =0
