A jetliner is landing with a speed of 69 m/s. Once the jet sets down, it has 750 m of runway to slow down to 6.1 m/s. What is the average acceleration during landing?

Acceleration is the rate of change in velocity with respect to time.
In other words, the change in velocity over the change in time.
a = (delta v) / (delta t)
but this formula wont help up too much in this problem.
To solve this problem, we can use this formula,
v_f^2 = v_i^2 + 2ad
Where v_f and v_i are the final and initial velocities respectively and a is the average acceleration experienced over the distance d.
We know the initial velocity, we know the final velocity, we know the distance the acceleration occurs over, just plug in and solve for the value of a.
