I need to see all the steps please! I know there are calculations of this kind of question out there.

An inquisitive physics student and mountain climber climbs a 51.0-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 2.02 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?

(c) What is the speed of each stone at the instant the two stones hit the water?

Explanation / Answer

mountain climber stands at the top of a 51.0 m cliff that overhangs a calm pool of water. He throws two stones vertically downward 1.0 s apart and observes that they cause a single splash. The first stone has an initial velocity of 2.02 m/s.

The 2nd stone must travel the 51.0 m downward in 1 second less than the 1st stone. Since both stones fall downward, I choose downward as positive direction.

Initial velocity = +2.02 m/s
Acceleration = +9.8 m/s^2
Displacement = +51.0 m
