Question

A jet Plane lands with a speed of 100m/s and deaccelerates at maximum rate of 5m/s^2 as it comes to rest can this plane land at small tropical island Airport where the runway is 800m long

Answer 1

Answer:

No it will not come to rest in 800 m long runway.

Explanation:

it would require 1000 m runway.

Answer 2

Answer:

vf=0m/svo=100m/sa=−5m/s2

The minimum time it takes to stop is,

vf=vo+at0=vo+atat=−vot=−voa=−100m/s−5m/s2=20s

b)In order to figure this out we apply the following formula;

v2f=v2o+2a(xf−xo)0=v2o+2a(xf)2axf=−v2ox=−v2o2a=−(100m/s)2−5m/s2=1000mor1km
