Question

A paratrooper moves downward with__________ acceleration???

Answer 1

uniform acceleration

Answer 2

A paratrooper moves downward with zero or with acceleration due to gravity.

A paratrooper while coming downwards will be obeying the laws of free fall. So, the acceleration acting above the paratrooper will be the ‘acceleration due to gravity’. As while coming down the paratrooper will not exhibit any other velocity except gravity which will be helping the paratrooper to reach the ground safely.

In free fall motion, the body which is falling downwards is said to have acceleration due to gravity which is represented as g and it exhibits a value of $9.8\ \mathrm{m} / \mathrm{s}^{2}$. As the paratrooper is coming down so the acceleration will be a positive value, which is acceleration due to gravity will be $\bold{9.8\ \mathrm{m} / \mathrm{s}^{2}}$.
