A metal box, attached to a small parachute, is dropped from a helicopter. Explain, in terms of the forces acting, why:

(i) Its velocity increased immediately after being dropped.

(ii) It reached a uniform velocity after a short time.

(i) because there's gravity force pulling it downwards.
(ii) because the force on the metal box is gone (either it has landed on the ground or something else happened) that means that the metal box is no longer moving but it has constant velocity/uniform velocity.
I'm sorry if it's wrong but that's how I see it

The metal box's velocity increases immediately after being dropped due to gravity, which pulls it downwards. It reaches a uniform velocity when air resistance balances out the force of gravity, resulting in no net force acting on it. This balance leads to what we call terminal velocity.
