scientists are experimenting with a king of gun that may eventually be used to fire  payloads directly into orbit. in one test, this gun accelerates a 3.8 kg projectile from rest to a speed of 5.2 * 10^3 m/s. the net force accelarating the projectile is 2.5 * 10^5 N. how much time is required for the projectile to come up to speed?
