Ajetliner, traveling northward, is landing with a speed of 69 m/s. once the jet touches down, it has 750 m of runway in which to reduce its speed to 6.1 m/s. compute the average acceleration (magnitude and direction) of the plane during landing.

Acceleration,

Explanation:

It is given that,

Initial speed of the jetliner, u = 69 m/s

Final speed of the jetliner, v = 6.1 m/s

Distance covered, s = 750 m

We need to find the average acceleration of the jetliner. It can be calculated using third equation of motion as :

So, the average acceleration of the plane during landing is . Hence, this is the required solution.

mistakes are ok

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
