Question

The same type of engine is placed in two different airplanes. The first airplane is twice as heavy as the second airplane. Which statement is correct about the mass of the airplane and its acceleration, assuming a constant net force?(1 point)
Responses

Increasing the acceleration of the airplane causes the engine to provide less force.
Increasing the acceleration of the airplane causes the engine to provide less force.

Decreasing the mass of the airplane will result in the airplane accelerating more.
Decreasing the mass of the airplane will result in the airplane accelerating more.

Answer 1

"Decreasing the mass of the airplane will result in the airplane accelerating more."

Reason: a = F/m. With the same net force, smaller mass gives larger acceleration (if one plane is twice as heavy, its acceleration is half that of the lighter plane).
