A skydiver who jumps out of a plane that has a forward velocity of 40 m/s. That means that the skydiver has a forward velocity of 40m/s. Ignore the air resistance.
What difference is there between the downward velocities of the skydiver who jumped out of the helicopter (with no forward velocity) and the one who jumped out of a plane (with a forward velocity of 40 m/s?
