Two stones are dropped from the edge of a 60-m cliff, the second
stone 2.0 s after the first. How far below the top of the cliff is
the second stone when the separation between the two stones is 40
m?
A stone is dropped from a bridge. A second stone is thrown
downwards 2.0 s later with an initial speed of 25 m/s. They both
reach the water below at the same instant. (a) How long did it take
for the first stone to reach the water? (b) How high is the bridge?
(c) What are the speeds of the two stones just before they hit the
water?
A stone is dropped from the top of a cliff. The splash it makes
when striking the water below is heard 2.5 s later. The speed of
sound in air is 343 m/s. How high is the cliff?
A stone is dropped from the roof of a building, 1.10s after that
a second stone is thrown straight down with an initial speed of
20.0 m/s & the two stones land at the same time
How high is the building h=???m
A 2 kg stone is dropped from a 50-m-tall building.
Simultaneously, a second 1 kg stone is thrown horizontally from the
building at a speed of 15 m/s, as shown in the figure.

On
the moon the acceleration due to gravity is -1.6 m/s. a stone is
dropped from a cliff on the moon and his the surface of the moon 40
seconds later.
How do i find the position function of the stone?
A student stands on the edge of a cliff and throws a stone
horizantally over the edge with a speeed "v1". The cliff is "h"
meters high. Given [h, v1]
a. The time for the stone to hit the ground
b. The horizantal distance the stone traveled while in the
air.
c. The magnitude and direction of the stone's velocity just
before hitting the ground
A student stands at the edge of a cliff and throws a stone
horizontally over the edge with a speed of vi = 10.0 m/s. The cliff
is h = 41.9 m above a body of water as shown in the figure below.
With what speed and angle of impact does the stone land?
A student stands at the edge of a cliff and throws a stone
horizontally over the edge with a speed of 10.0 m/s. the cliff is
50.0 m above a flat horizontal beach. (a) how long after being
released does the stone strike the beach before the cliff? (b) find
the speed just before the stone strikes the beach. (c) find the
traveling horizontal distance for the stone
A stone is dropped at t = 0. A second stone, with twice
the mass of the first, is dropped from the same point at t
= 234 ms.
How far below the release point is the center of mass of the two
stones at t = 326 ms? (Neither stone has yet
reached the ground.)

How fast is the center of mass of the two-stone system moving at
that time?
A stone is dropped at t = 0. A second stone, with 6
times the mass of the first, is dropped from the same point at
t = 130 ms. (a) How far below the release
point is the center of mass of the two stones at t = 350
ms? (Neither stone has yet reached the ground.)
(b) How fast is the center of mass of the
two-stone system moving at that time?
