If a body of mass m falling from rest under the action of gravity encounters an air resistance proportional to the square of the velocity, then the body's velocity t sec into dv the fall satisfies the differential equation m- mg-kv, where k is a constant that depends on the body's aerodynamic properties and the density of the air. (Assume dt that the fall is short enough so that the variation in the air's density will not affect the outcome...

172 = A free-falling object close to the surface of the earth accelerates at a constant rate g. Assuming that the upward direction is positive, the equation -9 is the differential equation governing the vertical height coordinate y(t) of the falling body at time t. Here t = 0 is taken to be the initial time when the object starts to fall. If we assume further that the object is tossed upwards from a height yo with an initial velocity...
