The average speed of a Nitrogen molecule in air is about 858 m/s, and its mass is about 4.68 × 10−26 kg.
If it takes 2.6 × 10−13 s for a nitrogen
molecule to hit a wall and rebound with
the same speed but in the opposite direc-
tion, what is the magnitude of the average
acceleration of the molecule during this time interval?
