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/s2 (12s - 0s)               (12s)
