The average speed of a nitrogen molecule in air is around 6.70 x 102 m/s, and its mass is around 4.68 x10-26 kg.
(i) When it takes 3.80 x 10-13 s for a nitrogen molecule to strike a wall and rebound with the same speed however moving in an opposite direction (supposed to be the negative direction), determine the average acceleration of the molecule throughout this time interval?
