Final answer:
To find the force exerted for the plane to fly, determine the acceleration of the plane from rest to 100 m/s in 25 seconds and calculate the force using the equation force = mass x acceleration.
Explanation:
To find the force exerted for the plane to fly, we can use the equation:
force = mass x acceleration
Given that the plane reaches a velocity of 100 m/s in 25 seconds, we can calculate the acceleration. Since the plane starts from rest, the initial velocity is 0 m/s.
Using the equation acceleration = (final velocity - initial velocity) / time, we find the acceleration to be 4 m/s². Substituting the values into the force equation gives us the force exerted by the plane to fly.
