##### Reference no: EM13527499

A jet plane lands with a speed of 88 m/s and can accelerate at a maximum rate of -4.40 m/s2 as it comes to rest.

a) From the instant the plane touches the runway, what is the minimum time needed before it can come to rest?

b) What is the actual minimum distance needed to stop the plane?

c) at what time after touchdown does the plane reach 1/2 the minimum distance determined above?
