A stuntman wearing a jetpack walks off the edge of the Hancock Tower in Boston, 241 meters above the ground. The stuntman is in freefall (starting from rest, vertically) until he reaches a certain height H above the ground, when he switches on the jetpack. Use g = 9.80 m/s. == Part (a) Homework Answered Due Sep 19th, 12:15 PM Assume the jetpack (when it is on) gives the stuntman a net upward constant acceleration with a magnitude of 3.60 g. If the stuntman wants to time the turning on of the jetpack so that he reaches the ground with a velocity of 0 m/s, at what height H should he turn on the jetpack? m Type your numeric answer and submit 52.4 - Answered Correct! 3 attempts left You are correct Resubmit Part (b) := Homework Answered Due Sep 19th, 12:15 PM What is the stuntman's maximum speed during the trip? m/s Type your numeric answer and submit 60.8 Answered Correct! 4 attempts left - You are correct Resubmit Part (c) [:= Homework Unanswered Due Sep 19th, 12:15 PM What is the total time it takes the stuntman to go from the top of the Hancock Tower to the ground?
