56! **Educational Text Transcription**---**Problem 56:**A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 25.0° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier’s mass is 55.0 kg, and the coefficient of kinetic friction between the skis and the snow is 0.120. Find the magnitude of the force that the tow bar exerts on the skier.**Problem 57:**A 44-kg chandelier is suspended 1.5 m below a ceiling by three wires, each of which has the same tension and the same length of 2.0 m (see the drawing). Find the tension in each wire.**Diagram Explanation:**The diagram associated with Problem 57 illustrates a chandelier suspended below a ceiling. Three wires of equal length (2.0 m) and equal tension support the chandelier. The wires form a symmetrical arrangement, with each wire making equal angles with the line directly upward from the chandelier to the ceiling. The distances involved, including the 1.5 m vertical distance from the chandelier to the ceiling, are clearly marked.---

Given: The slope is 25 degrees. The mass of the skier is 55.0 kg. The coefficient of friction is…

*56. A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 25.0° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 55.0 kg, and the coefficient of kinetic friction between the skis and the snow is 0.120. Find the magni- tude of the force that the tow bar exerts on the skier.
