Textbook Question

Chapter 9, Problem 68P

You’re working in quality control for a model rocket manufacturer. testing a class-D rocket whose specifications call for an impulse between 10 and 20 N·s. The rocket’s burn time is Δt = 2.8 s, and its thrust during that time is F(t) = at(t − Δt), where a = −4.6 N/s². Does the rocket meet its specs?
