My Notes Ask Your Te The average speed of a nitrogen molecule in air is about 6.70 x 102 m/s, and its mass is about 4.68 × 10-26 kg. (a) If it takes 2.90 x 10s for a nitrogen molecule to hit a wall and rebound with the same speed but moving in an opposite direction (assumed to be the negative direction), what is the average acceleration of the molecule during this time interval? 1.089 The response you submitted has the wrong sign. m/s (b) What average force does the molecule exert on the wall? 0.918 Your response differs significantly from the correct answer.

Explanation / Answer

Given,

v = 6.7 x 10^2 m/s ; m = 4.68 x 10^-26 kg

a)We know that

v = u + at

a = (v - u)/t

a = 2 x v/t = 2 x 6.7 x 10^2/2.9 x 10^-13 = 4.62 x 10^15 m/s^2

Hence, a = 4.62 x 10^15 m/s^2

b)F = ma

F = 4.68 x 10^-26 x 4.62 x 10^15 = 2.16 x 10^-10 N

Hence, F = -2.16 x 10^-10 N
