The equation of motion of a rocket, of massm, traveling vertically under a thrustFand air resistance or dragDis given by
Ifm= 1000 kg,F= 50,000 N,D= 2000v, andg= 9.81 m/s2, find the time variation of the velocity of the rocket,
using the initial conditionsx(0) = 0 andv(0) = 0, wherex(t) is the distance traveled by the rocket in timet.
