Solving a problem in physics section 10 point 57 mechan

57. On the inclined plane is a weight of 350 g, the upper side of the thread are tied. Her pull parallel to the inclined plane. When a tension force of 2.6 N load evenly glides up the ramp, and at a tension force of 1.5 N uniformly down. To determine the frictional force between the load and the plane and the angle of inclination to the horizontal plane.
