A small projectile (caliber, 9 mm) is fired vertically downward into a fluid medium with an initial velocity of 500 m/s. Due to the resistance of the fluid the projectile experiences a deceleration equal to a --0.6 v' m/s2, where v is in m/s. Determine the projectile's velocity 4 seconds after it is fired. You may neglect gravity! (2 points) 0
