Question

Космическая ракета стартует с космодрома с ускорением 45 м/с2.какую скорость она будет иметь после того как пролетит 1000м (подробное оформление

Answer 1

S=v(x)^2 -v(0)^2/2a ;v(0 начальная скорость =0
V(x)^2=2as= 9000. Извлекаем квадратный корень =300

Answer 2

Calculation of the Final Velocity of a Rocket

To calculate the final velocity of a rocket after it has traveled a distance of 1000 meters with an acceleration of 45 m/s^2, we can use the following equation of motion:

v^2 = u^2 + 2as

Where: - v is the final velocity - u is the initial velocity (assumed to be 0 in this case, as the rocket starts from rest) - a is the acceleration - s is the distance traveled

Substituting the given values into the equation, we have:

v^2 = 0^2 + 2 * 45 * 1000

Simplifying the equation, we get:

v^2 = 0 + 90000

Taking the square root of both sides, we find:

v = √90000

Calculating the square root, we get:

v ≈ 300 m/s

Therefore, the rocket will have a final velocity of approximately 300 m/s after traveling a distance of 1000 meters with an acceleration of 45 m/s^2.
