Question

Во время полета космонавт массой 70 кг ощущает перегрузку , равную 4. Найдите вес космонавта в этот момент.

Answer 1

4-кратная перегрузка даёт 4-кратный "вес" равный 280 кг. Только вес обычно измеряется не в кг, а в ньютонах F=4mg

Answer 2

Calculation of the Astronaut's Weight during the Flight

To calculate the weight of the astronaut during the flight, we need to use the formula for calculating weight:

Weight = Mass x Acceleration due to gravity

Given that the astronaut's mass is 70 kg and the acceleration due to gravity is approximately 9.8 m/s^2, we can calculate the weight of the astronaut.

Weight = 70 kg x 9.8 m/s^2

Using this formula, we find that the weight of the astronaut is approximately 686 N (Newtons).

Calculation of the Astronaut's Overload

The question states that the astronaut experiences an overload equal to 4. Overload is a measure of the force experienced by an object in relation to its weight. In this case, the overload is given as a multiple of the astronaut's weight.

To calculate the overload, we multiply the weight of the astronaut by the given overload factor:

Overload = Weight x Overload factor

Given that the overload factor is 4, we can calculate the overload experienced by the astronaut.

Overload = 686 N x 4

Using this formula, we find that the overload experienced by the astronaut is approximately 2744 N.

Calculation of the Astronaut's Weight during the Overload

To find the weight of the astronaut during the overload, we need to subtract the overload force from the total force acting on the astronaut.

Weight during overload = Total force - Overload force

The total force acting on the astronaut is equal to the sum of the weight and the overload force.

Total force = Weight + Overload force

Substituting the values we have calculated, we can find the weight of the astronaut during the overload.

Total force = 686 N + 2744 N

Total force = 3416 N

Therefore, the weight of the astronaut during the overload is approximately 3416 N.
