HELP!! ALL MY POINTS WILL BE GIVEN an airplane's speed at the time of landing is 90 m/s. ten seconds later it had a speed of 30 m/s. what was the acceleration of the airplane?

-6 m/s^2

Explanation:

30 - 90 = -60

-60 / 10 = -6

If acceleration was constant, it will be -6 m/s^2

If acceleration was constant, it will be -6 m/s^2

Explanation:

Hope this helped!!

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
