two identical pellet guns are fired simultaneously from the edge of a cliff. these guns impart an initial speed of 30.0 m/sec 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?
