Question

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?

magnitude | m/s |

direction | ---Select--- upward downward |

(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 |

**Here is what I solved before,
please modify the figures as per your question. Please let me know
if you have further questions. Ifthis helps then kindly rate
5-stars.**

**a) Vo*t + 0.5g*t^2 = d.**

**1****.92*t + 4.9*t^2 =
49.**

**4.9t^2 + 1.92t - 49 = 0.**

**Use Quadratic Formula and get:**

**t = 2.9714 seconds.
b. Vo*2.9714 + 4.9*2.9714^2 = 49.**

**Vo*2.9714 + 43.263 = 49.**

**2.9714*Vo = 49 - 43.263 = 5.7368.**

**Vo = 5.7368 / 2.9714 = 1.93068 m/s. ----> Intial
Velocity**

**Direction Vertically Downward**

**c. Vf^2 = Vo^2 + 2g*d.**

**Vf^2 = 1.92^2 + 19.6*49 = 964.086.**

**Vf = 31.049 m/s. = Final velocity.**

An inquisitive physics student and mountain climber climbs a
49.0-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
1.80 m/s.
(a) How long after release of the first stone do the two stones
hit the water?
(b) What initial velocity must the second stone have if the two
stones are to hit the water simultaneously?...

A person throws two identical stones from the top of a 200-m
high cliff overlooking a lake. Stone 1 is thrown at an angle of
30o above the horizontal with an initial speed of 40
m/s. Stone 2 is thrown at an angle of 30o below the
horizontal with an initial speed of 40 m/s. Neglect air
resistance.
Which stone hits the water first?
Stone 1.
They hit at the same time.
Stone 2.

A mountain climber throws a carabiner off the vertical face of a
cliff from a height h=27.2 m above the ground. The carabiner lands
a horizontal distance of 36.3 m away from the base of the cliff. If
the carabiner was thrown with an initial velocity that is
horizontal, what was its initial speed when thrown?

A mountain climber throws a carabiner off the vertical face of a
cliff from a height h=27.7 m above the ground. The carabiner lands
a horizontal distance of 45.8 m away from the base of the cliff. If
the carabiner was thrown with an initial velocity that is
horizontal, what was its initial speed when thrown? Select one:

A rock climber throws a small first aid kit to another climber
who is higher up the mountain. The initial velocity of the kit is
13.0 m/s at an angle of 69.0∘∘ above the horizontal. At the instant
when the kit is caught, it is traveling horizontally, so its
vertical speed is zero. What is the vertical height difference
between the two climbers?
