Two masses, m = 3.31 kg and m = 7.29 kg, are connect by a string of negligible mass. The string passes over a frictionless pulley so that m and m hang down on opposite sides of the pulley. The whole system is released from rest. Calculate the tension in the string as the masses are moving.

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).
