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 3.7-kg projectile from rest to a speed of 4.7 × 10³m/s. The net force accelerating the projectile is 1.5 × 10⁵ N. How much time is required for the projectile to come up to speed?
