An airplane traveling at 60 m/s comes to a stop in 10 seconds. whats the airplanes acceleration.

-6 m/s^2

Explanation:

acceleration = [velocity(final) - velocity(initial)] / time

Since the airplane is stopping, velocity(final) has to = 0 m/s.

velocity(initial) = 60 m/s

t = 10 seconds

So, a = (0-60)/10

a = -6 m/s^2

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

i think its d if wrong im sorry
