A small projectile is fired vertically downwards into a fluid medium with an initial velocity of 60 m/s.

a small projectile is fired vertically downwards into a fluid medium with an initial velocity of 60 m/s. due to the drag resistance of the fluid, the projectile experiences a deceleration of a = (-0.4 v^3) m/s2, where v is in m/s.
