Problem: A jet acquires a lift-off speed of 112m/s in 20.0s, starting from rest and traveling due east.
Part A: What are the magnitude and direction of its average acceleration?
Please show steps to find the magnitude and direction of its average acceleration.
The average speed of a nitrogen molecule in air is about 6.70 * 10^2 m/s, and its mass is about 4.68 * 10^-26 kg. What average force does the molecule exert on the wall
