An air-track glider with mass m1 is moving on a level, frictionless air track in the physics lab. The glider is connected to a lab weight with mass m2 by a tight, flexible, non stretching string that passes over a stationary, frictionless pulley.

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
