A jet plane lands with a speed of 110 m/s and
can decelerate uniformly at a maximum rate
of 4.1 m/s2 as it comes to rest.
Can this plane land at an airport where
the runway is 0.80 km long? Answer this by
calculating.
Answer in units of km

Since the question is yes/no, units don't matter much.
The first step is to see how long it takes to decelerate from 110 to 0 at 4.1/sec: 110/4.1 = 26.829 sec
Now, the distance traveled is 1/2 at^2 = 1/2 * 4.1 * 26.829^2 = 1475.58 m
Looks like it's gonna end up in the mud.
Or maybe in the terminal.
