A jet plane lands in an airport with a speed of 125 m/s and can accelerate uniformly at a maximum rate of -9.8 m/s2 as it comes to rest. What should be the minimum length of the runway so that the jet plane can land in the airport safely?

Answer 1

V^2 = Vo^2 + 2a*d
V = 0
Vo = 125 m/s
a = -9.8 m/s^2
Solve for d, the length.
