simple velocity/acceleration/distance equation--but is mastering physics wrong? A rock climber stands on top of a 57 -high cliff overhanging a pool of water. He throws two stones vertically downward 1.0 apart and observes that they cause a single splash. The initial speed of the first stone was 1.6 . i will give you time, they both hit the water 3.3 seconds after the first stone is released (this both mastering physics and I agreed upon) 1. the initial speed of the second stone 2. the speed of the first stone as it hits the water 3. the speed of the second stone as it hits the water so actually completed the questions, but the answers I got were different from the mastering phsyics answers--and I can't figure out how they got them. so if someone can scan these problems real quick and shoot their answers, id like to see if its mastering phsyics or me that is wrong.
