Write a program that receives distance and speed values for the plane and the closest moving object to the plane. The program must calculate the time to impact. If the time to impact, based on the parameters above, is less that 10s then the program will signal the plane to launch the passengers to safety.
Pseudo code:
Declare distance As double, planeSpeed As double, objectSpeed As double
Declare timeToCollision As double
INPUT distance
INPUT planeSpeed
INPUT objectSpeed
SET timeToCollision = distance / (planeSpeed + objectSpeed)
IF timeToCollision >= 10
OUTPUT “Safely averting the object” ELSE
OUTPUT “Ejecting passengers to safety” END IF Flow Chart:
Start
Distance As double, planeSpeed as double, objectSpeed as double
timeToCollision As double
timeToCollision = distance / {planeSpeed + objectSpeed}
if {timeToCollision >= 10
System.out.println("\nAvert object!"); System.out.println("\nEject passengers!");
End
