6. Scientists are experimenting with a kind of gun that may eventually beused to fire payloads directly into orbit. In one test, this gun acceleratesa 5.0-kg projectile from rest to a speed of 4.0 × 10' m/s. The net forceaccelerating the projectile is 4.9 × 10° N. How much time is required forthe projectile to come up to speed?
