A mountain climber stands at the top of a 35.0 m cliff that overhangs a calm pool of water. She throws two stones vertically downward 1.00 s apart and observes that they cause a single splash. The first stone had an initial velocity of -1.20 m/s. (a) How long after release of the first stone did the two stones hit the water? (Round your answer to at least two decimal places.)   (b) What initial velocity must the second stone have had, given that they hit the water simultaneously?   (c) What was the velocity of each stone at the instant it hit the water?
