We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

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).

Suppose an object in free fall is dropped from a building. its starting velocity is o m/s. what is the speed (in m/s) of the object falling after 2 seconds?
