A projectile is shot upward from the surface of Earth with an initial velocity of 82 meters per second. Use the position function below for free-falling objects. What is its velocity after 4 seconds? After 15 seconds? (Round your answers to one decimal place.) s(t) = -4.9t2 + vot + So 4 s m/s 15 s m/s
