Problem 1: A mass m is accelerated by a time-varying force exp(-ßt)v³, where v is its velocity. It also experiences a resistive force nv, where n is a constant, owing to its motion through the air. The equation of motion of the mass is therefore dv = exp(-ßt)v – nv. m dt Find an expression for the velocity v of the mass as a function of time, given that it has an initial velocity vo.
