Textbook Question

Chapter 2, Problem 19E

A model rocket is launched straight upward. Its altitude y as a function of time is given by y = bt − ct², where b = 82 m/s, c = 4.9 m/s², t is the time in seconds, and y is in meters. (a) Use differentiation to find a general expression for the rocket’s velocity as a function of time, (b) When is the velocity zero?
