www.twitch.tvThis physics question
oops
wrong one
A student walks off the top of the CN Tower in Toronto, which has height h and falls freely. His initial velocity is zero. The Rocketeer arrives at the scene a time of t later and dives off the top of the tower to save the student. The Rocketeer leaves the roof with an initial downward speed v0. In order both to catch the student and to prevent injury to him, the Rocketeer should catch the student at a sufficiently great height above ground so that the Rocketeer and the student slow down and arrive at the ground with zero velocity. The upward acceleration that accomplishes this is provided by the Rocketeer's jet pack, which he turns on just as he catches the student; before then the Rocketeer is in free fall. To prevent discomfort to the student, the magnitude of the acceleration of the Rocketeer and the student as they move downward together should be no more than five times g.
Ummm
Interesting
I hate this quiz
all quizes are online
that is one of 15 questions
that is the question
oh
ffs I am stupid
What is the minimum height above the ground at which the Rocketeer should catch the student?
lol
no real numbers here boys Kappa
variables all the way
Unless I am stupid, I would think the minimum is 5g/2t^2
hmmm
