Question

С какой силой давит космонавт массой 60 кг на опору при вертикальном взлете ракеты с ускорением 9 м разделить на с в квадрате? Во сколько раз вес космонавта больше силы тяжести?

Answer 1

P=m(g+g1);P=60*(10+9)= 1140 ,P/Fтяж= 1140/600=1.9

Answer 2

Calculation of the Force Exerted by the Astronaut

To calculate the force exerted by the astronaut, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, the mass of the astronaut is given as 60 kg, and the acceleration of the rocket during vertical takeoff is given as 9 m/s^2.

Using the formula F = m * a, we can calculate the force exerted by the astronaut:

F = 60 kg * 9 m/s^2

F = 540 N

Therefore, the force exerted by the astronaut on the support during vertical takeoff is 540 Newtons.

Comparison of Astronaut's Weight and Force of Gravity

To determine how many times the weight of the astronaut is greater than the force of gravity, we need to compare the force exerted by the astronaut (540 N) with the force of gravity acting on the astronaut's mass.

The force of gravity can be calculated using the formula F = m * g, where m is the mass of the astronaut and g is the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s^2.

Using the formula F = m * g, we can calculate the force of gravity acting on the astronaut:

F = 60 kg * 9.8 m/s^2

F = 588 N

Therefore, the force of gravity acting on the astronaut is 588 Newtons.

To determine how many times the weight of the astronaut is greater than the force of gravity, we can divide the force exerted by the astronaut by the force of gravity:

540 N / 588 N = 0.918

Therefore, the weight of the astronaut is approximately 0.918 times greater than the force of gravity.
