From your chemistry class, you know that the most common speed of a nitrogen molecule is 700 m/s. The molecules' velocity is pointed along random directions, but some molecules head straight up; i.e. directly away from the Earth's center. Consider the thickness of the atmosphere as the highest point that such a nitrogen molecule can fly to, if it goes straight up. What is the altitude? mA.Two motor vehicles, BMW and Ducati, are driving at SLEX southbound lane. At 9:00:00 am they are 100 meters apart and both having a velocity of 100 km/hr with BMW on the lead.
