I have to design a procedure which will allow me to calculate the applied force(thrust) of a stomp rocket. We are allowed to use tools to find measurements. So far, I have calculated the height that the rocket reached (22.5) m using trig. (right angle triangle where one angle is 66 degrees and the adjacent length is 10m), the mass of the rocket (14.29g) and the mass of the person stomping on the rocket (104 pounds) I now don't know how to calculate the applied force of thhe stomp rocket used to thrust/accelerate it through the air. Help please!

This is simple with a CBL equipment (computer based lab), it has a force detector. IT measures force vs time. You put the "rocket in a stand, with a upper block preventing if from leaving, put the force detector at the top, and "launch" the rocket. THe computer measures force vs time, graphs it, and integrates it to give total impulse. Ask your teacher if this equipment is available.

Failing that, any measurement is pretty weak. You need not only force, but time (rockets gain impulse (force*time)).

The pressure in the launch tube changes very rapidly, I doubt if you could read it on a pressure gauge.

Have you tried measuring the initialvelocity of the rocket with high speed camera, your camera in movie mode probably can help in that, frame by frame. That intial velocity is a sure measure of the impulse given to the rocket.

To calculate the applied force (thrust) of a stomp rocket, you can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = m * a).

In this case, the mass (m) refers to the total mass of the rocket and the person stomping on it. Since you've provided the mass of the rocket (14.29g), it is essential to convert the mass of the person from pounds to kilograms (kg) for consistency.

To do this, follow these steps:

1. Convert the mass of the person from pounds to kilograms.
- 1 pound ≈ 0.4536 kilograms.
- Multiply the mass of the person in pounds (104 pounds) by 0.4536 to get the mass in kilograms.

2. Calculate the total mass (m) of the system.
- Add the mass of the rocket (converted to kilograms) and the mass of the person (converted to kilograms).

Now that you have the total mass (m) of the system, further steps are required to calculate the applied force (thrust).

3. Calculate the acceleration (a) of the rocket.
- To find the acceleration, we need to know the change in velocity and the time it took to reach that velocity.

4. Determine the change in velocity.
- This can be calculated using the height the rocket reached (22.5 m) and the initial velocity (0 m/s) since it started from rest.

5. Calculate the time it took for the rocket to reach the given height.
- To calculate this, it is necessary to know the initial velocity, the acceleration due to gravity (9.8 m/s^2), and the height reached.
- You can use the kinematic equation: vf^2 = vi^2 + 2aΔx, where vf is the final velocity, vi is the initial velocity, a is the acceleration, and Δx is the change in position.

Finally, with the acceleration (a) and the total mass (m) of the system known, you can determine the applied force (thrust) using Newton's second law of motion (F = m * a).

Remember to double-check all the units and conversions to ensure the calculations are consistent.
