A jet plane lands with a speed of 110 m/s and can accelerate with a maximum magnitude of 7.00 m/s2 as it comes to rest.
(a) From the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest?
(b) Can this plane land on a small tropical island airport where the runway is 0.800 km long?
(c) What is the minimum distance the plane requires to land?
