Question 1
What would be the length of the takeoff run (ft)?
GIVEN INFORMATION:
Use "g" = 32.2 ft / s2
1 knot = 1.69 ft / s
Gross Weight = 20,000 pounds
Average Drag = 1,500 pounds
Average Friction Force = 500 pounds
Average Thrust = 10,000 pounds
Lift Off Speed = 130 KTAS
655 feet
1870 feet
1644 feet
3650 feet
Question 2
According to the universal gas law,
temperature changes do not affect density or pressure.
pressure is proportional to changes in temperature but not density.
density is always constant with either temperature or pressure changes.
density in proportional to pressure changes and inversely proportional to temperature changes.
