The 1st supersonic flight was peformed by CAPT.CHARLES YEAGER in 1974.He flew at a speed of 300m/s at an altitude of more than 12,where the speed of sound in air is slightly less than 300m/s.Suppose CAPT. YEAGER accelerated from 120m/s to 300m/s in 25.0s.What was the magnitude of his accelebration?

magnitute = size, or number
a = change in V / change in time
a = 180 m/s / 25 s
(180 (m / s)) / (25 s) = 7.2 m / s^2

Change in Velocity = Acceleration x Time
300 m/s - 120 m/s = Acceleration x 25.0s
Accerlation = 180m/s / 25.0s
= 36/5 = 7.20 m/s/s

Yaeger was old and retired in 74. He poked a hole in the sound barrier in 1947.

Thats EASY, yea im in physics to...so here's what you do....
you do 300-120 which equals 180 then you do 180 divided by 25.0 and that = 7.2 and so your answer is 7.2m/s
Your welcome! bye bye!

total change in velocity over total change in time.
