If an airplane is moving at a constant velocity of 400 m/s for 20 s, what is its acceleration during this period?
0 m/s squared
20 m/s squared
40.82 m/s squared
need more information

wouldnt it be need more information because isnt acceleration ending velocity minus starting velocity divided by the time, or can it be 20 m/s squared where 400 was over 20 s
