The average speed of a nitrogen molecule in air is about , and its mass is . (a) if it takes for a nitrogen molecule to hit a wall and rebound with the same speed but moving in the opposite direction, what is the average acceleration of the molecule during this time interval? (b) what average force does the molecule exert on the wall?

a)  a = - 2 v₀ / t   b)  F = -2m v₀ / t

Explanation:

In this exercise, the molecular nitrogen reaches the wall with a velocity v and bounces with the same magnitude, but in the opposite direction, let's use kinematics to find the average acceleration

      = v₀ + a t

     a = ( -v₀) / t

    = - v₀

     a = (- v₀ -v₀) t

    a = - 2 v₀ / t

b) to find the average force let's use the impulse concepts

     I = F t = Δp

    F t = m- m v₀

    F = m (-v₀-v₀) / t

    F = -2m v₀ / t

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
