Physics Force & Laws Of Motion Level: Misc Level
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 5.0 kg projectile from rest to a speed of 4.5 x103 m/s.The net force accelerating the projectile is 5.5 x105N. How much time is required for the projectile to come up to speed?
