Question

A paratrooper after opening of his parachute experiences:
a) Retardation
b) Acceleration
c) Equilibrium
d) Speed ​

Answer 1

He experiences acceleration.

• The air receptivity overcomes the descending gravity pull after the parachute is unfolded. The dropping paratrooper's acceleration is tnen upwards.
• A downward falling item would slow down if it were subjected to an upward net pull.
• As a result, the trooper slows down. As its speed drops, the quantity of air resistance reduces as well, until the trooper reaches maximum velocity once more.
