Question

При выводе спутника на орбиту, проходящую вблизи поверхности Земли, была совершена работа 3,2*10 в 10 степени. Найти массу спутника.

Answer 1

Известно, что у исскуственного спутника Земли должна быть скорость v=8000 м/с:

E{k}=m*v²/2;

m=2E{k}/v²;

m=1 кг.

 

Ответ: 1 кг.

Answer 2

для того чтобы спутник был искуственным спутником земли необходимо что бы его скорость была 8000м/с

следовательно:

К=m*$v^{2}$/2

m=2К/$v^{2}$

m=1кг

Ответ:1 кг

 

 

 

Answer 3

Calculating the Satellite's Mass

To calculate the mass of the satellite, we can use the formula for the gravitational force between the satellite and the Earth. The formula is given by:

F = (G * m1 * m2) / r^2

Where: - F is the gravitational force - G is the gravitational constant (approximately 6.674 * 10^-11 N m^2/kg^2) - m1 and m2 are the masses of the two objects (in this case, the Earth and the satellite) - r is the distance between the centers of the two objects

Given that the work done to place the satellite in orbit is 3.2 * 10^10 J, we can use this energy to find the satellite's kinetic energy and then its velocity. From there, we can calculate the satellite's mass.

Finding the Kinetic Energy and Velocity of the Satellite

The kinetic energy of the satellite can be calculated using the formula:

KE = (1/2) * m * v^2

Where: - KE is the kinetic energy - m is the mass of the satellite - v is the velocity of the satellite

By rearranging the formula, we can solve for the velocity:

v = sqrt((2 * KE) / m)

Calculating the Mass of the Satellite

Using the given work done and the kinetic energy formula, we can find the velocity of the satellite. Then, we can use the velocity to calculate the mass of the satellite.

Let's proceed with the calculations.
