Review A sailboat can be propelled into the wind by a maneuver called beating to windward. Beating requires the sailboat to travel in a zigzag pattern at an angle to the wind that is greater than the no-go zone, which is shaded red in (Figure 1). When a sailboat is just outside the no-go zone (boats B in the figure) the wind Part A exerts a force F on the sail that has a component in the direction of motion v. Similar comments apply to boats C. The work done by the wind on the sail is W = Fdcose, and because v = d/t, the propulsion power P = W/t delivered to the sailboat is Fvcose, where 0 is the angle between the sail force and the Assuming that F and v have the same magnitudes for each sailboat, will the propulsion power delivered to sailboats B be greater than, less than, or the same as the propulsion power delivered to sailboats C? direction of motion.

Between two ski hills, there is a valley. Hill l is 735m and the second hill is 625m. From point A to point B, a skier skis. The skier starts at rest at point A and finishes at rest at point B. Between the two points, the total length of the path is 4.11m with an average slope of 40 degrees from the horizontal. a) Sketch the free body diagram and show all the forces on the skier. Indicate the location where the gravitational potential energy is equal to zero on the diagram. b) assuming the system is skier and the earth, and there is friction involved between the ski and the snowy ground ( coefficient of kinetic friction), determine the thermal energy that is lost to the surrounding when the skier is skiing from point A to point B in terms of variables, m, L and theta c) Calculate the value of coefficient of kinetic friction between snow and ski which would make the skier stop at the top of the lower point B
A medium-sized jet has a 3.8-m-diameter fuselage and a loaded mass of 85,000 kg. The drag on an airplane is primarily due to the cylindrical fuselage, and aerodynamic shaping gives it a drag coefficient of 0.37. Part A How much thrust must the jet's engines provide to cruise at 240 m/s at an altitude where the air density is 1.9 kg/m³? Express your answer with the appropriate units.
