Air drag and acceleration (not gravity)

Click For Summary
SUMMARY

The discussion focuses on calculating air drag acting on a rocket during its flight, given specific parameters such as thrust, maximum height, and time of flight. The maximum height achieved by the rocket is 76 meters, with a time of thrust of 0.8 seconds and a total time of flight until velocity reaches zero of 4.96 seconds. The mass of the rocket is 0.08 kg, resulting in a gravitational force (Fg) of 0.8 N. The challenge lies in determining air drag during the upward acceleration phase, as traditional formulas primarily relate to velocity, which complicates the calculations.

PREREQUISITES
  • Understanding of Newton's laws of motion

In physics class we made a rocket and test fired it. Now we are given the thrust and we found out the max height of the rocket and the time of flight.

Max Height = 76m
Time of thrust/ upward acceleration = .8s
Time of flight with only gravity acting until velocity is 0 . = 4.96s (not including downward fall)
Mass of rocket = 0.08 kg
Fg= 0.8N
g= 9.8m/s^2

Now we are supposed to find the air drag acting on the object. But I have no clue on how to do that because all the formulas relate to velocity, which is not really a given because the rocket is accelerating upwards. So is there a formula that I can use to solve this?

4.96 seconds is the time it took for velocity to be 0, ... reach maximum height
