Answer 1

Ответ:

В момент раскрытия парашюта человек подвергается действию инерционных сил,и он испытывает момент перегрузки

Answer 2

Parachutist Experiencing Overload or Weightlessness

When a parachutist is descending with a parachute, they are experiencing weightlessness. This is because the force of gravity is being counteracted by the aerodynamic drag of the parachute, resulting in a net force of zero and the sensation of weightlessness for the parachutist.

The sensation of weightlessness is due to the fact that the parachutist is falling at a constant velocity, known as the terminal velocity. At this point, the forces of gravity and air resistance are balanced, resulting in no acceleration and the feeling of weightlessness for the parachutist.

In contrast, overload occurs when the force experienced by an object is greater than the force of gravity acting on it. This typically happens during rapid acceleration or deceleration, such as during takeoff or landing in an aircraft, or when a vehicle accelerates quickly. However, during a normal parachute descent, the parachutist is not experiencing overload, as the forces are balanced, resulting in weightlessness
