Rocket acceleration, how high does it go?

In summary, rocket acceleration is the rate at which a rocket's speed increases over time and is achieved through burning fuel in the rocket's engines, causing thrust. Factors such as the amount and type of fuel, engine design, and weight of the rocket affect its acceleration. The maximum height a rocket can reach also depends on these factors, with higher acceleration resulting in a greater height. However, there is a limit to rocket acceleration due to air resistance and gravity, and the rocket will eventually reach a constant speed known as its terminal velocity.

A model rocket is fired upward. The rocket's average initial acceleration is 44.5 m/s2 until the fuel burns out in 0.835 s. How high does the rocket go? Ignore the effects of air friction.

I was thinking about using the equation x=x(initial)+V(initial)*t+1/2at^2

Welcome to PF;
Before thinking about the equation to use, start out by describing the physical processes the rocket will go through. After the fuel burns out, what happens? i.e. can you sketch a v-t diagram for the motion?
 

Related to Rocket acceleration, how high does it go?

1. What is rocket acceleration?

Rocket acceleration is the rate at which a rocket's speed increases over time. It is typically measured in meters per second squared (m/s^2).

2. How does rocket acceleration work?

Rocket acceleration is achieved by burning fuel in the rocket's engines, which produces thrust. This thrust propels the rocket forward and causes it to accelerate.

3. What factors affect rocket acceleration?

The amount and type of fuel, the design of the rocket's engines, and the weight of the rocket all affect its acceleration. The more fuel a rocket has, the stronger its acceleration will be.

4. How high can a rocket go with its acceleration?

The maximum height a rocket can reach depends on various factors such as the strength of the rocket's engines, the amount of fuel it carries, and the aerodynamics of the rocket. In general, the higher the acceleration, the higher the rocket can go.

5. Is there a limit to rocket acceleration?

Yes, there is a limit to rocket acceleration. As a rocket travels higher into the Earth's atmosphere, air resistance and gravity will gradually slow it down. Eventually, the rocket will reach a point where it can no longer accelerate and will maintain a constant speed, known as its terminal velocity.
