Question

will he come down with the same speed without parachute?

Answer 1

No he will not come down with the same speed without parachute. This is so because parachute stops air and reduces the speed of him while falling down .

Answer 2

No,he will not come down with the same speed as the parachute because parachute traps the air and the air current of the trapped air exert an upward force on the parachute,which acts opposite to the gravitational pull.If the parachute is absent,the gravitational pull won't be reduced and thus gravity will be more powerful and attract him more fast and his speed will accelerate at the speed of 9.8 m/s^2.
