A rocket is traveling at 2000 m/s. It changes velocity to 3000 m/s at a rate of 50 (m/s)/s. How long does it take for this to happen?

Question

(Find elapsed time, t)

Since the abbreviation for seconds is "s" put your answer in this format:

XX s

Answer 1

a = Δv/Δt ⇒

 

Δt = Δv/a = [(3000 - 2000) m/s] / (50 m/s²) = 20 s
