A runway used for landing only is used by two types of aircraft, one with an airspeed of 120 knots (nautical miles/hr) and the other with an airspeed of 150 knots. The length of common approach path is 6 nautical miles. A minimum distance separation of 3 nautical miles must be maintained by aircraft on the common approach path. Runway occupancy time for both types of aircraft is 60 seconds.a. Use space-time diagrams to determine the time separations (in seconds) at the runway threshold for each aircraft pair. Present your results in matrix form.b. If 40 percent of the aircraft travel at 120 knots and 60 percent at 150 knots, and the buffer matrix below is used (data in seconds), what is the capacity of the runway in aircraft per hour?Speed of lead aircraft120 knots 150 knotsSpeed of trailing 120 knots 3315aircraft 150 knots 3333

The rope is 16 m long and the tree limb is 8 m above the man's center of gravity where he holds the rope. Suppose that the man begins at rest right next to the child and backs away with an acceleration of 0.2 m/s^2.
The gases are expanded to 140 kPa with a reversible adiabatic process. Calculate the work done by the gases, assuming they can be approximated by air with constant specific heats.
the three forces of magnitude P can be replaced by a single, equivalent force R acting at point A. Determine the distance x and the magnitude and direction of R
How much (in addition to your trade-in value) can you afford to spend for a car averaging 30 mpg You expect to drive 15,000 mile/year and expect gasoline to cost $4.00/gallon and you will keep he car 10 years. Your personal interest rate is 6%/yea..
Data from service records show that the time to repair a certain machine is normally distrubuted with a mean of 65 min and a standard deviation of 5 min. Estimate how often it will take more than 75 min to repair a machine.
A 3000-lb car is traveling on a paved road with Cd (coefficient of drag) = 0.35, Af (frontal area of the vehicle) = 21ft^2, and p(air density)=0.002378 slugs/ft^3. Its engine is running at 3000rpm and is producing 250ft-lb of torque.
if point D is at (100,100) and the line DE to "E" is 300 feet long at an azimuth of 225 degree , what is location of point E in the XY coordinate system. what is the length and azimuth of the line connection points (100,100) to (300,500)
