Question

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:

Answer #1

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 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?

1) Enrique throws a stone horizontally from a cliff that has a
vertical distance of 30.0m from where Enrique releases the stone to
the base. The initial horizontal velocity of the stone is 6.00m/s.
Apply concepts of Projectile Motion to determine
a) the horizontal distance, from the base of the cliff, the
stone strikes the ground,
b) the velocity of the stone after it has fallen 10.0m. Apply
the Conservation of Mechanical Energy to determine
c) the magnitude of the...

Rock thrown off a cliff
You want to know the height of a cliff so you throw a rock off the
edge with an initial speed of 18.5 m/s inclined at an angle 30.3°
above the horizontal. You have a friend that records that it takes
3.4 s for the rock to hit the bottom of the canyon after it is
thrown. For the following questions, call up the positive
y direction and make the positive x direction
horizontal and...

eddy throws a little sand bag so that is lands on the top of a
vertical post that is 4m high. The post is 1.3 m away from eddy. He
releases the bag from a height of 1.5m above the ground. The
initail speed of the bag is v=7.5 m/s, the angle between the
velocity and the horizontal is 80 degrees. you can neglect the
friction due to the air.
How long does the sand bag stay in the air?...

A projectile is shot off of a cliff at an angle of 30◦ with
respect to the horizontal. The projectile reaches a height of 7.0m
above the cliff. The object hits the ground 15m from the base of
the cliff. A) Find the initial velocity. B) Find the height C) Find
the magnitude and direction of the projectile’s velocity just prior
to it reaching the ground.

A student stands at the edge of a cliff and throws a stone
horizontally over the edge with a speed of
v0 = 17.5 m/s.
The cliff is h = 26.0 m above a flat, horizontal beach
as shown in the figure.
A student stands on the edge of a cliff with his hand a height
h above a flat stretch of ground below the clifftop. The
+x-axis extends to the right along the ground and the
+y-axis extends up...

A ball is thrown toward a cliff of height h with a speed of 33
m/s and an angle of 60 ? above horizontal. It lands on the edge of
the cliff 3.7 s later.
How high is the cliff?
What was the maximum height of the ball?
What is the ball's impact speed?

Astronaut Mary is standing at the edge of a vertical cliff a
distance h above horizontal ground on a distant planet. She
performs an experiment where she throws a magnetized steel ball
horizontally off the cliff with initial speed v. After leaving
Mary’s hand, the ball undergoes a horizontal displacement D before
landing on the ground. Only gravity acts on the ball during this
flight. Mary repeats this experiment. However, during this 2nd
experiment, a strong magnet is placed nearby...

A ball is thrown toward a cliff of height h with a
speed of 30 m/s and an angle of 60∘ above horizontal. It lands on
the edge of the cliff 3.0 s later.

b) What was the maximum height of the ball?
c) What is the ball's impact speed?
