A compound machine is set up as shown in the diagram. An inclined plane makes an angle of 30° with the horizontal and has a length of 5.0 m. A smooth, frictionless pulley is fixed at the top of the plane. A block B of mass 2.0 kg rests on the plane and is attached to a light rope that passes over the pulley and is attached to a hanging mass H of mass 5.0 kg. The free end of the rope is wound around a circular handle of radius 0.20 m which is turned by a person. The person applies a tangential force on the handle, causing the system to move at a constant speed of 0.50 m s⁻¹ up the plane. Using the information in the diagram, answer the following:
