a bullet is fired from a gun that is 2.0 meters above flat ground. the bullet emerges from the gun with a speed of 250 m/s.
a) how long does the bullet stay in the air before it hits the ground?
b) At what horizonatal distance from the firing point does the bullet strike the ground?
i know i need to do horizontal and vertical components, but after that im lost.
