How long will it take for a rocket to pass through a 150 m deep shaft if the rocket is 50 m long and the speed is 72 km / h?

Let’s go to the frame of reference associated with the end of the rocket.
Then this end of the rocket needs to travel the distance S + l = 200m = S2
Let’s translate V into m / s:
72000 * 3600 = 20m / s
t = S2 / V = 200/20 = 10s
