Homework Help: PHYSICS

Posted by Tom on Sunday, March 16, 2014 at 12:38pm.

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 8.9-kg projectile from rest to a speed of 4.2 103 m/s. The net force accelerating the projectile is 1.4 105 N. How much time is required for the projectile to come up to speed?

Thanks :)
