An object of mass 'm' is on an inclined plane with an incline angle of 'O.' The object is moving down the incline at a constant speed. The free-body diagram is shown with the weight vector resolved into parallel and perpendicular components. (NOTE: Force vectors are not drawn to scale.) Which mathematical statements are correct? Include all that apply. a. Fnorm = Fperpendicular b. Fnorm = Fgrav C. Fnorm > Fperpendicular Ffrict Fnorm d. Fparallel = Ffrict e. Fparallel > Ffrict f. Fparallel
