Scientist 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 7.1 kg projectile from rest to a speed
of 2.9 x 10^3 m/s. The net force accelerating the projectile is 7.8
x 10^5 N. How much time is required for the projectile to come up
to speed?
