please help me provide argument that both may be correct

(ARG) A student accelerates a sied from rest carrying his little sister. The sled and sister have a total mass m, the coefficient of kinetic friction between the sled and the ground is u, and the student pulls so that the rope connected to the sled has a constant tension force T that makes an angle @ with the horizontal Suppose that the student increases the angle @ slightly while keeping the same Tension T in the rope, Two other students debate how this will change the magnitude of the sled's acceleration. Student A suggests that increasing the angle will increase the acceleration of the sled. Student B suggests that increasing the angle will decrease the acceleration of the sled
