Hey guys I need some help, I am struggling in a PH100 class and my professor is not that much help.
This problem puzzles me and I have been working on it all night.
"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 4.7 103 m/s. The net force accelerating the projectile is 5.9 105 N. How much time is required for the projectile to come up to speed? "
We are currently studying force, but I am lost how to find time using Newton's laws?
Thanks!
