According to Newton's law:
F = ma
Therefore:
a = F / m
Acceleration of rocket due to its thrust will be then
a = 3.3 * 107 / 2.9 * 106 = 11.38 m/s2.
If you consider rocket starting from some gravitational well(like Earth's), you have to take into account gravitational acceleration at the point(g for Earth's surface) that acts opposite(if rocket is facing away the mass centre, else it's a little more complicated) to find out net acceleration at the moment.
For rocket in our example, standing upright on the surface of Earth, net acceleration would be about 11.38 - 9.81 = 1.57 m/s2.

A rocket ship leaves earth's atmosphere. Its Initial velocity is less than its final velocity. What is this an example of?
Reduced atmospheric drag at higher altitudes, Acceleration due to the thrust of the rocket's engine(s).
A rocket engine that provides the initial thrust for a launch and is then discarded is called what?
Booster stage
During a rocket launch whioch is greater thrust of the rocket engine or weight of the rocket?
thrust of the rocket engine
As a rocket travels upwards the engine thrust remains constant but the mass of the rocket decreases Why?
The primary answer is that a rocket under constant acceleration is using up fuel, so it's mass decreases as the fuel is spent.
How could a toy rocket accelerate after takeoff?
As long as the thrust is more than the weight of the rocket (toy or otherwise) the rocket will accelerate. When the thrust matches the weight, the rocket will cruise. When the thrust is less then the rocket will slow.
How do you calculate acceleration in space?
Same as anywhere else. You can use the formula F = ma (force equals mass times acceleration) and solve for acceleration (a = F/m). Force might be gravitation, in specific cases - or the thrust from the rocket engine. Of course, SOME data must be known to figure out acceleration.Same as anywhere else.

What are two ways to increase the amount of thrust a rocket produces?
If the mass flow rate through the rocketâ??s engine is increased, then the thrust will be higher. Another way to increase the thrust amount is to increase the exit or initial velocity during takeoff.
How do you increase accelaration of a rocket in space?
F = M A whence A = F/M .Acceleration is directly proportional to the force applied to the rocket, and inverselyproportional to the rocket's mass. If you need to increase the acceleration, you havetwo choices . . . either reduce the rocket's mass, or increase the force applied to it.That means you must either toss something overboard, or else burn fuel faster.There's no other way.
A rocket becomes progressively easier to accelerate as it travels upward from the ground mainly because?
The rocket's acceleration is created by the net force acting on it. There are three forces acting on the rocket: the thrust provided by the engines, gravity or weight, and air resistance. The acceleration is inversely proportional to the rocket's mass. This is Newton's Second Law: (acceleration) = (net force) / (mass) We need to think about the direction of the forces. The thrust acts upward (call this positive), and both gravity and air resistance acts downward (call these negative). So we get (acceleration) = (thrust - weight - air resistance) / mass A typical rocket engine will provide constant thrust as long as the fuel lasts. But as the engine consumes fuel, expelling the exhaust products out the back of the rocket, the rocket's mass decreases. This tends to increase the rocket's acceleration since acceleration is inversely proportional to the mass. In addition to the decreasing mass, the rocket's weight decreases as it moves farther from the center of the Earth--- this effect is described by Newton's Law of Gravity. The rocket's decreasing weight tends to increase its upward acceleration. The action of air resistance is more complicated, and ordinarily we ignore air resistance in simple models just to avoid the complication air resistance gives to the problem. In the standard air resistance model, air resistance scales with the square of the rocket's speed and the air density. The rocket is moving faster and faster, but the air density is also decreasing as it rises through the atmosphere. I think we can safely say the air resistance force decreases as the rocket gains altitude, but a detailed answer illustrating precisely how this force changes would require a numerical simulation. Hope this helps!
What is a launch vehicle and how does it work?
a launch vehicle is the initial vehicle (rocket) that provides the package, weather it be humans or cargo, enough thrust and force to exit the atmosphere.
Is thrust a verb?
It can be as in "He thrust his sword into his enemy", however it can also be a noun as in "The thrust of the rocket was enormous".
