Question

I'm attempting to calculate acceleration for the following:

A plane lands on a runway with a speed of 120 m/s, moving east, and it slows to a stop in 12.0 s. What is the magnitude and direction of the plane's average acceleration during this time interval?

So far I've gotten to this point:

(0m/s - 120m/s)= (-120m/s)= stuck here.. the answer must be in m/s^{2}

(12s - 0s) (12s)

Step 1

Initial velocity of the plane is 120 m/s towards east and finally, the plane stops, that is, the final velocity of the plane is 0 m/s. The time required for stopping by the plane is 12.0 s.

Step 2

The average acceleration during the time interval of Δt can be calculated as,

Step 3

Here, the negative sign represents that the direction of...
