Question

I need help with part C (ii and iii)

b. The Boeing 737 - 800 aircraft can accelerate from rest to a take- off speed of 300 kmhr- in 25 seconds. Calculate in ms-2 the value of this acceleration, assuming it to be constant HINT: 1km = 1000m and 1hr = 3600s. kmhr means km divided by hr C. i. The aircraft has a mass of 6 x 104 kg. Two identical jet engines provide a thrusting force. Calculate the magnitude of the thrusting force needed to give the aircraft the acceleration calculated in bart (b). Hence find the thrust

i. The aircraft has a mass of 6 x 104 kg. 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 thrust (force) for EACH engine ii. The thrust calculated in (i) is a theoretical value. Suggest a reason why this thrust if applied IN PRACTICE (real life) would NOT provide this expected acceleration iii. 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?
