During the second stage of a rocket launch the rockets upward velocity increases from 980 m/s to 9000 m/s with an average acceleration of 33 m/s*.
How long did the acceleration last??
To determine the duration of the acceleration, we can use the formula:
v = u + at
Where:
v = final velocity (9000 m/s)
u = initial velocity (980 m/s)
a = acceleration (33 m/s^2)
t = time
Rearranging the formula:
t = (v - u) / a
Substituting the given values:
t = (9000 m/s - 980 m/s) / 33 m/s^2
t = 8020 m/s / 33 m/s^2
t ≈ 243.03 seconds
Therefore, the acceleration lasted approximately 243.03 seconds.
