Question

Космический корабль массой 1*10(в 6 степени) КГ поднимается с Земли вертикально вверх. Сила тяжести равна 1*10(в 7 степени) Н , сила тяги равна 3*10(в 7 степени). С каким ускорением поднимается корабль?

Answer 1

Найду ускорение по формуле
a=F/m
F=Fт-P=Fт-mg
a=(Fт-mg)/m=(30000000-1000000*10)/1000000=20
Ответ: 20 

Answer 2

Calculation of the Acceleration of the Spacecraft

To calculate the acceleration of the spacecraft, we need to consider the forces acting on it. In this case, we have the force of gravity and the thrust force.

The force of gravity acting on the spacecraft is given as 1*10^7 N This force is directed downwards.

The thrust force, which is the force generated by the engines of the spacecraft, is given as 3*10^7 N This force is directed upwards.

To calculate the net force acting on the spacecraft, we need to subtract the force of gravity from the thrust force:

Net force = Thrust force - Force of gravity

Net force = 3*10^7 N - 1*10^7 N

Net force = 2*10^7 N

Now, we can use Newton's second law of motion to calculate the acceleration of the spacecraft. Newton's second law states that the acceleration of an object is equal to the net force acting on it divided by its mass:

Acceleration = Net force / Mass

The mass of the spacecraft is given as 1*10^6 kg.

Substituting the values into the equation:

Acceleration = (2*10^7 N) / (1*10^6 kg)

Acceleration = 20 m/s^2

Therefore, the spacecraft is accelerating upwards with an acceleration of 20 m/s^2.
