Textbook Question
Chapter 2, Problem 74P
You’re at mission control for a rocket launch, deciding whether to let the launch proceed. A band of clouds 5.3 km thick extends upward from 1.9 km altitude. The rocket will accelerate at 4.6 m/s2, and it isn’t allowed to be out of sight for more than 30 s. Should you allow the launch?
