Question

Космическая ракета стартует вертикально вверх с ускорением 20 м/с2. Масса ракета 1500т. Определить силу тяги ракетных двигателей.

Answer 1

Ответ:

F - mg = ma ; F = m ( a + g ) ; P = F = 90 * ( 20 + 10 ) = 2700H .

Answer 2

Calculation of Thrust Force

To calculate the thrust force of the rocket engines, we can use the formula:

Thrust Force = (Rocket's Mass) x (Acceleration)

Given: - Rocket's Mass = 1500 tons = 1,500,000 kg - Acceleration = 20 m/s^2

Using the given values, we can calculate the thrust force:

Thrust Force = 1,500,000 kg x 20 m/s^2

Thrust Force = 30,000,000 Newtons

Therefore, the thrust force of the rocket engines is 30,000,000 Newtons.

This calculation is based on the provided information and the formula for calculating thrust force
