The aircraft has a mass of 6x 104kg. two identical jet engines provide a thrusting
force. calculate the magnitude of the thrusting force needed to give the aircraft
the acceleration calculated in part (b). hence find the corresponding thrust for
each engine
the thrust calculated in () is a theoretical value. suggest a reason why this thrust
if applied in practice would not provide the expected acceleration.
the mass of the aircraft was increased by loading additional passengers and
luggage. how could this affect the time taken to reach take-off speed?

Explanation:

I assume the acceleration calculated in part (b) is the 3.33 m/s² from your other question.

Use Newton's second law to find the total force:

F = ma

F = (60,000 kg) (3.33 m/s²)

F = 200,000 N

Since there are 2 engines, the thrust from each is half of this:

F = 100,000 N

In reality, there are forces other than thrust.  There are also drag forces (rolling friction and air resistance).

From Newton's second law, if we increase the mass and keep the force the same, the acceleration decreases.  So it would take longer to reach the take-off speed.

the results is a decrease in air temperature with an increase of altitude.
