Respuesta :
855 feet
Step-by-step explanation:
Step 1 :
Speed of the aircraft moving vertically is -55 feet / sec
Time period for which the stunt should last = 15 seconds
Distance at which the stunt should stop = 30 feet above the ground
Step 2 :
Distance moved by the aircraft in 15 secs = 15 * 55 = 825 feet
At the end of 15 seconds the aircraft should be 30 feet above the ground
So the stunt should be started at the altitude of 15 * 55 + 30 = 855 feet
