Wing Loading of = 570 N/m² Co = 0.06 +0.0150₂² The glider was launched at 500 meters altitude. Calculate for mimimum rate of descent in meters per second. (Round off answer with two decimal places, No units, No commas) Answer given: 23554 Which is not true about the effect of altitude? A. Points with the same value of a therefore must have the same glide path angle. B. The drag polar changes with flight speed. C. The glide path angle is independent of altitude and depends solely on the angle of attack.
What is not true about the clean airplane configuration? A. It means simply that the wing flaps and landing gear are retracted, as these are the cause of drag due to the lack of streamlined shape. B. It is defined as an airplane in its cruise configuration. C. It is when flaps or spoilers are deployed and gear down indicating the aircraft is configured for slower flight like when landing or taking off D. It is the flight configuration of a fixed-wing aircraft when its external equipment is retracted to minimize drag, and thus maximize airspeed for a given power setting.
Step by step work starting with the formula. Q1. Find the net force on an object of mass 30 kg that is falling in air and experiences a force due to air resistance of 50 newtons. Q2. A tiny particle of mass 4 x 10-4 kg (so fdrag = bv) has a drag coefficient, b = 3.3 x 10-2 kg/sec. What is this particle's terminal velocity? At terminal velocity, bvterm = mg, where b is the drag coefficient, m is the mass, v is the terminal velocity and g is the acceleration due to gravity.
VI. Does kinetic friction depend on the normal force? 21. Make a prediction. If normal force increases, does the kinetic friction increase, decrease, or stay the same? Give a reason r your prediction. 22. Use the Larger Area. Place the larger area of the block on the track. Record the hanging mass in the data table. Add a 500g rectangular block on top of the wood block. Change the hanging mass to 500g 23. Run the Experiment. Hang the 500g mass over the pulley. Repeat the experiment as before. 24. Change the Normal Force. Add a second 500g rectangular block on top of the block. Record the total mass in the data table. Perform the experiment again. 25. Change the Normal Force Again. Repeat the experiment by adding another 500g rectangular block on top of the block. Record the total mass. If the block does not move at all or stops after moving a short distance, add more mass to the hanging mass.
