A 1120 kg airplane starts from rest and accelerates forward at an average rate of 2.8 ms2 for 10 s along a runway that is 250 m long What is the average forward force on the airplane during this Tim?

F=m.a
The weight of the plane for all intents and purposes remains constant.
Since you're already given the average acceleration, that is a constant as well.
Therefore the average force is the product of the two. Regardless of the other data.
You can do the maths.

What physics is involved when you're being pushed backwards during takeoff?
You're not being pushed backwards.You're feeling the FORWARD force that the seat is applying to you in order to accelerate your body forward.

How does thrust help an airplane fly?
Thrust is the force that provides an airplane its speed. Thrust must be brought to a certain level and maintained in order for the plane to move at a speed that is sufficient to create lift from the wings.
Who invented the airplane during the Industrial Revolution?
The Wright brothers invented the airplane during the Industrial Revolution.
What is the speed of an airplane if it travels 600km in 3 hours?
Its average speed during that period of 3 hours is 182.27 feet per second. (rounded)
What happenes During activities requiring aerobic endurance?
Your heart accelerates and your blood preasure rises.
What are the four forces acting on an airplane during flight?
Thrust - The aircraft being pulled (or pushed) forward through the air. Drag - The aerodynamic friction slowing down the aircraft's forward movement. Lift - The lifting force of the wing. Weight - The force of gravity pulling the aircraft towards the ground.

Yes.
What angle does an airplane take off at?
This varies depending on the design of the airplane, the weight of the airplane, and the weather conditions encountered during the takeoff, but is typically from 9 - 20 degrees nose up for jets.
