A jet starts from rest at t0 = 0 s and travels along the runway with a constant horizontal acceleration of 1.6 m/s2 . It reaches its liftoff speed of 80 m/s and takes off.

a. What is the minimum runway length Lmin needed for the jet to lift off starting from rest?

Lmin =

b. How long does it take to lift off from rest?

t1 - t0 =

c. What is the average velocity of the jet from rest to liftoff?
