Two47.identical pellet guns are fired simultaneously from the edge of a cliff.These guns impart an initial speed of 30.0 m/s to each pellet. Gun A isfired straight upward, with the pellet going up and then falling backdown, eventually hitting the ground beneath the cliff. Gun B is firedstraight downward. In the absence of air resistance, how long after pelletB hits the ground does pellet A hit the ground?48. mmh An astronaut on a distant planet wants to determine its accel-eration due to gravity. The astronaut throws a rock straight up with a ve-locity of +15 m/s and measures a time of 20.0 s before the rock returnsto his hand. What is the acceleration (magnitude and direction) due togravity on this planet?I52. A ball is thrown straight upward. At 4.00 m above its launch point,the ball's speed is one-half its launch speed. What maximum heightabove its launch point does the ball attain?53. ssm From her bedroom window a girl drops a water-filled balloonto the ground, 6.0 m below. If the balloon is released from rest, how longis it in the air?
