[SOLVED] Physics problem w/ guns
Two identical pellet guns are fired simultaneously from the edge of a cliff. These guns impact an initial speed of 30.0 m/s to each pellet. Gun A is fired straight upward, with the pellet going up and then falling back down, eventually hitting the ground beneath the cliff. Gun B is fired straight downward.
In the absence of air resistance, how long after pellet B hits the ground does pellet A hit the ground?
when i look at this i saw that they only gave us 2 pieces of information
there's gravity and initial velocity i believe
