If the mass of the rocket is 20,000 kg, then its weight is (m g) = (20,000 x 9.8) = 196,000 newtons.
That's the downward force acting on it.
What we want is an upward acceleration of 1 m/sec2.
The sum of all forces on it is F = m A, with A = +1.
F = (20,000) x (+1) = 20,000 newtons upward.
The sum of the forces on the rocket is
(Fgravity + Fengines) = (-196,000) + Fengines = 20,000
Fengines = 216,000 newtons, upward
Notice that immediately after blast-off, the required force immediately decreases. As fuel is
burned off, the mass of the rocket begins to decrease. In practice, the force of the booster
engines remains constant, and the rate of acceleration grows as the mass decreases.
Length is not measured in "per second".
That's a rocket with two stages- when the first stage (or section) runs out of fuel, it separates from the top half (second stage) and falls away, leaving that second stage to fire up, and drive the rocket higher.
Team rocket has a woobat that they caught in the third or fourth (or second ;) ) episode.
A Diwali rocketis ejecting 0.05 Kg of gases per second at a speed of 400m/s. What is the accelerating force on the rocket.

The rocket speed increases every second because of the continuous burning of fuel, which generates thrust that propels the rocket forward. As the fuel is burned and expelled as exhaust, the rocket becomes lighter, allowing it to accelerate due to the conservation of momentum. Additionally, there is minimal air resistance in space, enabling the rocket to accelerate more efficiently.
Before the second one.

The v-2 rocket was the first long range rocket in the world. The rocket was developed in the second world war.
around 5 miles per second on its way to uranus
The second rocket to reach space was the V-2 rocket, which was launched by Germany in 1944. This was a significant milestone in the development of rocket technology and paved the way for future space exploration.
