A model rocket is launched straight upward. Its altitude y as a function of time is given by y=bt−ct2, where b = 80m/s , c = 4.9m/s2 , t is the time in seconds, and y is in meters.
1. Use differentiation to find a general expression for the rocket's velocity as a function of time.
2. When is the velocity zero?
Express your answer using two significant figures.
