Scientists are experimenting with a kind of gun that may eventually be used to fire payloads directly into orbit. In one test, this gun accelerates a 6.2-kg projectile from rest to a speed of 3.1 × 103 m/s. The net force accelerating the projectile is 4.8 × 105 N. How much time is required for the projectile to come up to speed? Type your answer here  Units Choose your answer here
