If a 2 kg paper airplane is pushed by the wind with a force of 5n, how fast will the paper
airplane accelerate?

It will accelerate at a rate of 2.5 m/s².

Explanation:

Given:

Mass of the paper airplane is,

Force acting on the airplane by wind is,

As per Newton's second law of motion, net force is the product of mass and acceleration. So,

Therefore, the airplane will accelerate at a rate of 2.5 m/s².

conservation of mass

mass before something happens = mass afterwards
