Captain Jack Sparrow is pushing a treasure chest across the wooden deck of his trusty ship, The Black Pearl. The chest is much shorter than he is, so his applied force makes an angle of 55.0° below the horizontal. The coefficient of kinetic friction between the chest and the deck has a value of 0.366, and the chest has a mass of 219 kg. Draw a diagram showing all of the forces that are acting on the chest. If a force needs to be broken up into components, show the components and formulas for the components.
