A 2-stage rocket is video-recorded. The video gives the following data: Light (from combustion) of 1st stage: occurs at 0.1 seconds Sound of 1st stage: at 7.7 seconds Light out of 1st stage: 7.9 s Light (from combustion) of 2nd stage: 11.8 s Sound ends from 1st stage: 19.33 s Sound of 2nd stage: 29.4 s Speed of sound at the elevation the rocket was launched: 335 m/s Question 1: A) How far away in meters is the camera? C) What is the velocity (m/s) of the rocket at the end of the 1st stage? D) What is the acceleration (m/s^2) of the 1st stage?

A 2-stage rocket is video-recorded. The video gives the following data:

  • Light (from combustion) of 1st stage: occurs at 0.1 seconds
  • Sound of 1st stage: at 7.7 seconds
  • Light out of 1st stage: 7.9 s
  • Light (from combustion) of 2nd stage: 11.8 s
  • Sound ends from 1st stage: 19.33 s
  • Sound of 2nd stage: 29.4 s
  • Speed of sound at the elevation the rocket was launched: 335 m/s

Question 1:

A) How far away in meters is the camera?
C) What is the velocity (m/s) of the rocket at the end of the 1st stage?
D) What is the acceleration (m/s^2) of the 1st stage?
E) What is the height of the rocket in meters after the 1st stage ends?

Question 2:

A) What is the height of the rocket in meters when the 2nd stage starts?
B) What is the velocity (m/s) of the rocket when the 2nd stage starts?
