Ajet makes a landing traveling due east with a speed of 120 m/s .
if the jet comes to rest in 13.5 s , what is the magnitude of its average acceleration?
what is the direction of its average acceleration? east, west, north or south?
i actually can figure this out if i knew the equation : (

Average acceleration over a time interval lasting is

where is the difference in the jet's final and initial velocities. It's coming to a rest, so

so the average acceleration has magnitude 8.9 m/s^2 and is pointing West (the direction opposite the jet's movement, which should make sense because the jet is slowing down).

answer: 0
