An inquisitive physics student and mountain climber climbs a 48.0-m-high cliff that overhangs a calm pool of water. he throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. the first stone has an initial speed of 2.18 m/s. (a) how long after release of the first stone do the two stones hit the water? s (b) what initial velocity must the second stone have if the two stones are to hit the water simultaneously? magnitude m/s direction (c) what is the speed of each stone at the instant the two stones hit the water? first stone m/s second stone m/s
