Question

A jet plane lands with a velocity of 100 m/s and can accelerate at a maximum rate of -5.0 m/s2 as it come to rest. Can this plane land at an airport where the runway is 0.80 km long?

Answer 1

s= [(v(fin) ² -v(init)²]/2•a=( 0-10000)/2•(-5)= 1000 m
This jet needs the plane land of the length 1000 m

Answer 2

s= [(v(fin) ² -v(init)²]/2•a=( 0-10000)/2•(-5)= 1000 m
This jet needs the plane land of the length 1000 m
