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

- physics -
**Steve**, Friday, September 23, 2011 at 4:12pmSince 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.
