1. The problem statement, all variables and given/known data A package of mass m is released from an aircraft flying horizontally with a velocity v0. In addition to gravity, a drag force acts on the package given by F=-[tex]\lambda[/tex]v. Find the i and j components of the velocity as a function of the time (t) from when the package was released. 2. Relevant equations F=ma 3. The attempt at a solution Acceleration in x-direction: F=ma(x) -[tex]\lambda[/tex]v(x)=ma(x) a(x)=-[tex]\lambda[/tex]v(x)/m dv(x)/dt = -[tex]\lambda[/tex]v(x)/m The solution method then integrates, and gets: v(x) = v0exp(-[tex]\lambda[/tex]t/m) I don't know how to do the integration. Thanks.
